A Metro Transit driver was attacked Tuesday by a man who boarded the bus in Minneapolis. A video, posted to social media, captured the unprovoked attack along with the laughter of a passenger.

"It's nothing short of disgusting," said Metro Transit spokesman Howie Padilla. "This operator's whole job is to get people to school, to the hospital, to wherever they need to go. He's just doing his job and then someone decides to board the bus, assault him, [then] up and leave."

The Route 5 driver pulled up to a bus stop at Emerson and 15th avenues about 3:45 p.m.

A man wearing a blue T-shirt boarded and immediately punched the driver in the body and face multiple times. The driver was treated for cuts and bruises at Hennepin County Medical Center and released.

Metro Transit investigators discovered the video of the attack overnight, Padilla said.

"No one can look at this video and not be disgusted by the unprovoked attack," Padilla said. "It just brings an emotional response."

Anyone with information about the incident is asked to call 612-349-7222.
