CALGARY, Alberta - Police say two young men died and six others were injured after using their personal sled/toboggan to go down a luge-bobsled track after hours at the Canada Olympic Park in Calgary.

Calgary police said Saturday that emergency crews received a call from an employee at the WinSport Canada facility in northwest Calgary at 1:30 a.m. after a report of several injured people on a closed track.

Insp. Kelly Campbell says that part way down the track the male teenagers hit a large gate that's used to separate the luge and bobsled tracks.
