“He’s easily the most hated man in Toronto,” said Alex Jansen, a filmmaker who has been working on a documentary about Mr. Kenk for more than a year as part of a study of his rundown neighborhood’s transition to hipsterdom. “But I just found that it’s not as black and white as I originally thought.”

Mr. Kenk was something of an informal social worker, Mr. Jansen explained, giving work to street people and outpatients from a nearby mental health institution. Of course, the police say some of that work involved stealing bicycles.

That was just the beginning. An additional 200 bikes were seized in Mr. Kenk’s home. Ten landlords around the city reported that their garages had been rented by Mr. Kenk and were bulging with bicycles. As the police gathered the mounds of bikes, they also found cocaine, crack cocaine, about 15 pounds of marijuana and a stolen bronze sculpture of a centaur and a snake in battle.
