A man who tried to parachute off a Calgary office building is in hospital after smashing through a window on the 24th floor, sending broken glass flying through seven windows in the atrium below.

Police say they were called to the Canada Trust building in downtown Calgary about 11:10 p.m. Thursday night.

They found the 41-year-old parachutist on top of a pedestrian walkway.

He was taken to hospital with non-life-threatening pelvic, abdominal and back injuries.

Charges are pending, according to police.

Emergency officials say it appears the man got caught in a wind current, carrying him into the building instead of away from it as he tried to parachute off in what is known as a BASE jumping stunt.

BASE stands for buildings, antennae, spans and earth. This type of jumping is an extreme sport that involves leaping from a fixed object such as a building, bridge or cliff with a parachute.

Police say the Calgary stunt caused about $5,000 damage to the building.
