Two teen brothers are dead and six others injured following a late-night accident on the bobsled track at the Canada Olympic Park in Calgary.

Twin brothers Jordan and Evan Caldwell, 17, died at the scene after a group of teens broke into the facility and used a “personal sled” on the bobsled track early Saturday morning, police said.

“Part way down, the group hit a large gate used to separate the bobsled and luge tracks,” police said in a statement.

The other six teenagers were taken to hospital with injuries ranging from minor to serious, police said in a statement, adding that the nature of their injuries made it difficult to identify “many” of the victims.

"We were reminded today that life is but a vapor. Life is precious, life is fragile, and we must redeem the time we’re given," the Caldwell family said in a statement.

"Our boys Jordan and Evan were bright lights to all who knew them. We are grieving their loss but confident in their new home of heaven."

Police said CCTV footage was being reviewed and investigators were working to determine how the teens entered the facility, which hosted events at the 1988 Winter Olympics.
