A retired FBI executive says a minor fender bender near West Town Mall turned into a humiliating months-long ordeal after she was arrested for DUI, jailed, strip searched, and later cleared by lab tests showing no alcohol or drugs in her system, according to a WVLT News investigation reported by Harry Sullivan.
Sullivan reported that Allison Tsiumis, a Lenoir City resident and 33-year veteran of the FBI, is now suing Knoxville Police Officer Christian Ferreras and the City of Knoxville in federal court.
Tsiumis claims Ferreras rushed the DUI arrest, fabricated evidence, and violated her civil rights. The DUI charge was dismissed months later after Tennessee Bureau of Investigation lab reports came back negative for both alcohol and drugs.
“There was no alcohol in my system,” Tsiumis told Sullivan. “There were no drugs in my system. My civil rights were violated, and that’s why I am taking this to the next level.”
A Fender Bender Becomes A DUI Arrest
Sullivan reported that the case began on Father’s Day weekend last year, when Tsiumis was involved in what she described as a minor fender bender while driving near West Town Mall in Knoxville.
No one was hurt, and Tsiumis said the two vehicles only exchanged some paint. She told Sullivan she expected police to help the drivers exchange insurance information and move on with their day.
Instead, she said the encounter changed when Officer Christian Ferreras arrived and quickly began asking whether she had been drinking or had taken anything.
“The almost immediate suggestion that I had been drinking was very surprising, shocking, and I denied it to him,” Tsiumis said. “Yet he continued to press on that.”
In body camera footage described in Sullivan’s report, Ferreras can be heard saying he smelled a faint odor of an alcoholic beverage.
Tsiumis’ lawsuit claims that was not true and that Ferreras fabricated smelling alcohol. Later lab tests showing no alcohol or drugs in her system are now central to her civil rights case.
That is what makes the case so troubling. A police officer’s stated observations can carry enormous weight in a DUI arrest, but if those observations are wrong or exaggerated, the person accused can spend months trying to undo the damage.
Field Sobriety Test Questions
Sullivan reported that Tsiumis said Ferreras spent only about a minute talking to the drivers before moving into field sobriety testing.
The lawsuit claims those tests were not properly administered.
Tsiumis specifically raised concerns about the pen light Ferreras used during one of the tests, saying it flashed on and off during the exercise.
“The pen light he was using flashed on and off intermittently, and I raised that to his attention three times,” Tsiumis said.
In the body camera footage, she can be heard saying, “Light’s off again. Light’s off again.”
Tsiumis told Sullivan that Ferreras did not respond to her concerns about the light, even though the test required her to follow it.
She also said the officer never told her whether she passed or failed the field sobriety tests. He simply handcuffed her.
“He did not tell me that I failed it,” she said. “He did not tell me that I passed it. He just handcuffed me.”
Field sobriety tests are meant to help officers assess impairment, but they are also subjective and can be affected by nerves, lighting, medical issues, road conditions, or even flawed instructions. That is why cases like this raise larger questions about whether officers should rely more heavily on immediate, objective testing when alcohol is the stated suspicion.
A Retired FBI Career Collides With A Jail Booking
Sullivan reported that Tsiumis spent more than three decades with the FBI, where she served in leadership and intelligence roles.
That background made the experience of being booked into jail especially painful.
Tsiumis told Sullivan that she never tried to “pull that card” during the roadside stop, even after being placed in handcuffs. But once she was taken into custody, the reality of being processed like an inmate hit hard.
The lawsuit says she was booked into the Knox County Detention Facility, strip searched, issued jail clothing, fingerprinted, photographed, and held for more than 12 hours before release.
“You know, being told to disrobe in front of a female deputy was humiliating as well, all the way down to naked,” Tsiumis said.
She described being given old jail clothing, including underwear she believed had been worn by others.
“It was just unreal, just stressful, traumatic,” she said.
For someone who worked proudly for the FBI for 33 years, the fingerprinting process carried an extra sting. In the written version of Sullivan’s report, Tsiumis said her fingerprints were being sent to the same organization where she had built her career.
That detail gives the story a strange full-circle sadness. A woman who once helped serve the country through law enforcement was suddenly sitting on the other side of the system, accused of a crime lab results later said she did not commit.
The Ignition Interlock Ordeal
Sullivan reported that the case did not end when Tsiumis left jail.
Her lawsuit says bond conditions required her to install an ignition interlock device, a breathalyzer system connected to her car. The device is meant to prevent a vehicle from starting unless the driver provides a sober breath sample.
Tsiumis said she was shocked that she had to use such a device before any conviction, especially since she maintained she had not been drinking.
In the written report, Tsiumis said the device included a breathalyzer, digital camera, and GPS monitoring, which made the ordeal humiliating and prolonged beyond the arrest itself.
She also said the device malfunctioned and disabled her car in traffic.
According to Sullivan’s report, the car shut down in a busy intersection, creating another dangerous and embarrassing moment that led to another police response.
Tsiumis said that interaction went differently. The responding officer was compassionate and professional, and he saw that she blew a zero on the device.
That moment is telling. A simple breath test, available in real time, showed she had not been drinking. Tsiumis’ case is now part of a wider conversation in Tennessee about whether officers should have better roadside tools before making DUI arrests.
Attorney Says The Case Is About The Fourth Amendment
Sullivan reported that Tsiumis’ attorney, Wesley Clark, said the lawsuit is not based on some novel legal argument.
“We’re not inventing some new legal theory to pursue these civil rights violations,” Clark said.
Clark said false DUI arrests and malicious prosecutions of innocent Tennesseans violate the Fourth Amendment, which protects people from unreasonable searches and seizures.
“That’s pretty basic,” he said.
The federal complaint claims unlawful arrest and malicious prosecution. Tsiumis is seeking damages and wants a jury to decide the case.
These lawsuits matter because a DUI arrest is not a small event, even when the charge is later dismissed. It can affect a person’s job, reputation, finances, mobility, and mental health. The delay between arrest and exoneration can itself become part of the punishment.
Tsiumis said she wants Tennessee lawmakers and law enforcement leaders to take the issue seriously.
“If it could happen to me, it could happen to anyone, and it has,” she said.
Knoxville Police Say An Internal Investigation Is Underway
Sullivan reported that WVLT reached out to the Knoxville Police Department for comment.
KPD spokesperson Scott Erland said the department takes allegations of this nature extremely seriously and that an internal investigation into the arrest referenced in the lawsuit is ongoing.
“The matter is being investigated thoroughly and will be addressed in accordance with departmental standards and policy,” Erland said.
The City of Knoxville declined to comment in the written version of the report, according to Sullivan.
No judgment has been made in the lawsuit, and the allegations against Ferreras and the city still have to be tested in court.
Still, the facts that Sullivan reported are difficult to ignore: Tsiumis was arrested for DUI, booked into jail, and forced to fight the charge for months before lab results showed no alcohol or drugs in her system and the case was dismissed.
Part Of A Larger Tennessee Pattern
Sullivan noted that this is the third sober DUI case WVLT has reported on in East Tennessee in the past month alone.
That detail gives Tsiumis’ story broader public importance. If this were one unusual case, it would still matter deeply to the person affected. But when similar stories keep appearing, the question becomes whether the system itself needs change.
Tsiumis said she hopes leaders across disciplines will address the problem, from law enforcement training to roadside testing tools to accountability when arrests are not supported by evidence.
That is a reasonable request. Impaired driving is dangerous, and police should stop drunk or drugged drivers before they hurt someone. But that mission loses public trust when sober people are arrested and left waiting months for lab results to clear their names.
The balance should not be hard to state: arrest impaired drivers, but do not shortcut probable cause, ignore contrary evidence, or let weak observations become life-disrupting charges.
Tsiumis’ FBI background may make her case stand out, but her warning is that it should not take a former federal executive to be heard.
The system, she says, needs to protect everyone.
