A retired FBI employee spent over 12 hours in jail and six months under bond restrictions for a DUI charge, only to have toxicology results prove she had zero alcohol or drugs in her system when Knoxville police arrested her.
False Arrest Leads to Federal Lawsuit
Allison Tsiumis, who dedicated more than 30 years to the Federal Bureau of Investigation, filed a lawsuit Monday against the Knoxville Police Department and the arresting officer. The June 15, 2025 arrest near West Town Mall followed a minor traffic accident. Despite claiming to smell alcohol, the officer found no open containers, prescription medications, or drug paraphernalia in her vehicle. Tsiumis consented to a blood test, confident in her sobriety. The officer administered field sobriety tests, including the Horizontal Gaze Nystagmus and Walk-and-Turn tests, which the lawsuit claims were improperly conducted before making the arrest.
Detention and Bond Restrictions
Police held Tsiumis at the Knox County Detention Facility for more than 12 hours, releasing her after 2:30 a.m. As a bond condition, authorities required her to install an Ignition Interlock device and breathalyzer in her vehicle. This requirement forced the retired federal employee to navigate daily humiliation despite her innocence. She maintained the equipment for nearly six months while awaiting the Tennessee Bureau of Investigation’s official toxicology report. The December 4, 2025 dismissal confirmed what Tsiumis knew from the beginning: she had no alcohol or controlled substances in her system at the time of the traffic stop.
Constitutional Rights Violation
The federal lawsuit seeks a jury trial and monetary damages for the humiliation and financial losses Tsiumis suffered. Her legal team argues the arrest violated her Fourth Amendment right to freedom from prosecution without probable cause. The case raises questions about field sobriety test procedures and officer judgment when making DUI arrests. For a woman who spent three decades upholding federal law, the wrongful arrest and extended legal battle represent a serious breach of the constitutional protections she dedicated her career to defending. The lawsuit demands accountability for law enforcement officers who arrest citizens based on flawed assessments rather than concrete evidence.
