OVIEDO, FL (WFTV/CNN) - Drywall is the reason a man spent three months behind bars.
A false positive test result of drywall powder led the police to arrest a Florida man for possession of cocaine.
Oviedo police said Karlos Cashe had a white substance believed to be drugs on his driver seat and the floor underneath it when he was pulled over back in March.
"I know for a fact it's drywall because I'm a handyman. I said that continuously during the arrest stop," Cashe said.
The arrest report showed Cashe was initially pulled over for driving without lights.
The sergeant then saw Cashe was on probation for marijuana and cocaine charges from Dec. 2015 which he pleaded no contest.
Cashe was then placed in handcuffs after the teletype system, which gets records from the criminal justice system, showed he was out after curfew.
Hours later, police learned their system wasn't up to date and Cashe wasn't breaking curfew.
But while Cashe was in the back of a patrol car, a drug detection K-9 unit arrived and signaled there were drugs in the car and the sergeant field tested what he believed to be crack, cocaine and marijuana.
When those tests came back positive, Cashe went to the Seminole County jail.
"I sat there 90 days knowing I was innocent," Cashe said.
Since Cashe was accused of violating probation, he wasn't allowed to bond out.
But as soon as the Florida Department of Law Enforcement test was completed in May, it revealed no drugs were in his car.
Cashe just walked out of jail last week and is now asking for the police to start an internal investigation.
An Oviedo police spokesperson is working to find out if an investigation has begun.
