Police in Canada have confirmed that two teenage boys who died during a bobsledding accident at Olympic Park in Alberta over the weekend, had broken into the facility with friends.

The two 17-year-olds, Jordan Caldwell and his brother Evan, were killed when the bobsled they were riding Saturday night went out of control.

They were pronounced dead at the scene while six other young men were taken to the hospital after they went into the park after hours and tried to take a toboggan down a bobsled track.

"Partway down, the group hit a large gate used to separate the bobsled and luge tracks," Calgary Police Duty Staff Sgt Paul Wyatt told Canada's GlobalNews.

The Caldwell family issued a statement saying: "Our boys Jordan & Evan were bright lights to all who knew them."

"We are grieving their loss but confident in their new home of heaven. Our brief 17 years with them were a gift."

"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.

Some of the other boys' injuries are serious, and police say those injuries were making it difficult to identify those involved.

Police said: "Investigators are working to determine how the teens entered the property and what led up to the decision to enter the closed track."

WinSport Canada is cooperating with the investigation, including supplying any CCTV footage that may assist with determining how and why this occurred.

It has been confirmed that both of the Caldwell boys worked as Hill Ambassadors during last winter’s season.
