A man in his twenties was found dead in a bus shelter in Montreal on Tuesday.

A bus driver on a route that went past the corner of Berri St. and Ontario St. noticed the man sitting slumped in the bus shelter and flagged down a police officer to report the incident.

When the officer went to the shelter he found the man was dead for reasons that have yet to be determined.

It's not known how long the man was in the shelter, but that area is not very far from the Ilot Voyageur bus terminal and UQAM.

Police are investigating the area for any signs that indicate how the man died, but an autopsy will likely be needed to determine the reason for the death.
