A Canadian man threw cinder blocks at Moose Jaw police from an apartment roof on Saturday. He was eventually found stuck in a four-storey chimney.
Police were called to a high rise around 10 a.m., with reports of a suspicious man with a sword on the roof.
When they arrived to investigate, the man threw bricks at them and officers retreated while a negotiator was called in.
The man then fell down the chimney while trying to evade police and became stuck.
Emergency crews were able to free him.
Police said the unidentified man suffers from mental illness and was taken to hospital with minor injuries.
He faces charges of assaulting a police officer and mischief to property.
