Douglas Kelly, 49, was arrested after he took meth to the police to try and press charges against his dealer

A Florida man who was hoping to get his drug dealer arrested has found himself behind bars instead.

That's because Douglas Peter Kelly, 49, was convinced his methamphetamine was bad - and took it to the police station to prove it.

Kelly, of Hawthorne, called the Putnam County Sheriff's Office on Tuesday to report that he had suffered a 'bad reaction' to some meth he purchased the week before.

He believed the 'violent reaction' was proof that he had been conned and sold a different drug.

Kelly then told detectives that he wanted his stash tested so that he could 'press charges' against the dealer who sold him the drugs.

The detectives told Kelly they were more than happy for him to come into the sheriff's office to get the drugs tested in person.

Kelly drove to the station and turned in a 'clear, crystal-like substance wrapped in aluminum foil', according to police.

The substance tested positive for methamphetamine, and Kelly was taken into custody.

Kelly has been charged with possession of methamphetamine and was taken to the Puntam County Jail, where he is being held on $5,000 bond.
