Erie police and UPMC Hamot security personnel removed a deer Wednesday after it entered the hospital's main lobby through a revolving door.

Pennsylvania Game Commission Conservation Officer Larry Smith tranquilized the deer -- a buck he estimated weighed about 100 to 125 pounds.

The deer entered the main lobby at about 7:40 p.m., a UPMC Hamot security officer said.

The deer ran down a hall and began head-butting a door and window, a UPMC Hamot security officer said.

An Erie police officer tied its front and back legs to help restrain it.

Erie police, Hamot security and Hamot nurses wrapped the deer in blankets and wet towels to calm it. They kept it restrained until Smith arrived.

The deer had cuts on its head and near its antlers, Erie police said.
