A couple was found dead in an apparent attack by an aggressive grizzly bear in Canadas Banff National Park, officials said Sunday.

Park officials first received a report of a bear attack on Friday night and spent several hours traveling by ground to the parks Red Deer River Valley, where they found the couples bodies and a nearby bear early Saturday morning.

The response team arrived on-site at 1 a.m. and discovered two deceased individuals, Banff National park said in a statement on its Facebook page. While in the area, the response team encountered a grizzly bear that displayed aggressive behaviour, leading Parks Canada staff to euthanize the bear on-site to ensure public safety.

The bodies have been transported about 50 miles away to Sundre, Alberta.

The surrounding area has been closed to visitors until further notice.

While the names of the couple have not yet been released, one of their family members shared details about them and their extensive wildlife experience with CBC News .
