An internal police investigation has been launched into the arrest of a Newstalk 1010 host earlier this year.
John Downs was taken into custody after he started taking photos of a crime scene he came across on his way home from a friend's house.
He was told he was being arrested for assault because a fire employee and officer accused him of trying to hit one of them.
On January 18, Downs had a few drinks with his girlfriend and friends before getting on the King St streetcar.
When the vehicle passed a crime scene, Downs says he decided to get out to grab a few photos for the newsroom.
After snapping a couple of pictures, he was approached by a Toronto Fire employee who asked him to leave.
"I assured him I was not interfering with the scene and took a third photo," Downs says on his blog.
That's when Downs says the fire officer said he would call police over.
"After agreeing to hash things out with the officers, my phone was swiped from my hand, landing on the sidewalk below," he says.
Downs says an officer then came up to him and he was thrown face first on to the sidewalk. He was cuffed, placed into a cruiser and taken to a station.
In the meantime, he learned that the fire employee and officer were accusing him of putting his hand into a fist, ready to take a swing at one of them.
"It's absolutely ridiculous," he says. "Even with some alcohol in my system, there's no way that happened and I know for a fact it didn't."
"I've never hit a human being in my life, nor would I ever hit a firefighter or a police officer."
When he arrived at 14 Division, Downs says he was told he was arrested for assault and brought to the station because he was intoxicated.
After being interviewed by police, Downs was charged with public intoxication. An assault charge wasn't pursued.
Downs spent the night at 14 Division and was released the next morning.
He took the matter to court and a few months later, the public intoxication charge was dropped.
He is now making the story public because he says it's something that can happen to anyone.
"All it takes is for a couple of people of authority to decide what they saw happen that night, and that's pretty air tight," he says. "And it's their word against yours."
Police have now launched an internal investigation.
"The Toronto Police Service is investigating John Downs' allegations," police spokesman Mark Pugash says in a statement.
Toronto Police Association president Mike McCormack will join the Jerry Agar Show Tuesday morning to discuss the story.
