Calgary police are asking for the public's help to find a man responsible for causing about $3,000 worth of damage to a city bus last month.

A man got onto a Calgary Transit shuttle bus at 52nd Street and McKenzie Towne Link S.E. just before 11 p.m. on July 1 and demanded that the driver get going.

The driver informed him the bus was on a set schedule and wouldn't leave until the designated time.

In response, the man began continually pulling the "stop cord," forcing the driver to activate an emergency button on his radio to get help removing the man from the bus.

The man then got off the bus, turned and kicked the glass door, causing it to shatter.

Damage is estimated at $3,000.

The man is described as white, about five feet 10 inches tall and he was wearing a black baseball cap and a red shirt with the Detroit Red Wings logo on the front.

Anyone with information is asked to call police at 403-266-1234 or Crime Stoppers at 1-800-222-8477.
