Video footage of the moment a wild deer crashed through the window of a bus in Pennsylvania has gone viral.
The video shows the white-tailed deer jumping through the window of the bus before running amok in the aisle trying to find a way out.
The incident, which was initially reported in local press, happened in Pennsylvania, according to the Johnstown Tribune-Democrat newspaper.
Authorities said the driver watched as the animal ran in circles in the aisle in a frenzy.
County transportation spokesman Josh Yoder said it "just walked off the bus".
At the time the bus was carrying just one passenger, who was sat at the back away from the deer.
No injuries were reported.
