The administrator of an assisted living facility in Selkirk, Manitoba said she received a text early Monday morning from a staff member that a deer was running around inside of their building.

Ashley Martyniw, administrator of the Woodland Courts, didn't believe what she was hearing.

"I thought it was a joke at first," Martyniw told CBC News. "That was quite a surprise. I've never come across anything like this in 40 years working with seniors."

They called in the Royal Canadian Mounted Police, who said one of the deer lost its antlers when it entered the building by crashing through a glass door.

The deer was barricaded in the building's exercise room, where police spent an hour and a half attempting to get the deer to an open door to make its escape.

"The buck realized the wide open door was right in front of his nose and jumped away to freedom," police said in a Facebook post.

"The cause of the incident is still under investigation but officers have not ruled out the possibility that he saw an attractive Christmas deer decoration through the window," the post said. "The broken antler was seized. No humans were injured."
