A man wanted in the brutal assault of another man near a downtown Minneapolis light rail station was arrested Tuesday afternoon, hours after police released a photo of the suspect and tips from the public led them to him.

The department posted to its Facebook page Tuesday two stills from a store surveillance video that it said captured the suspect's face. The post was shared more than 300 times.

Within about five hours, police posted that the 29-year-old suspect had been arrested and booked into the county jail, while thanking their online followers for reposting the photos.

In keeping with its policy, the Star Tribune isn't naming the man because he hasn't been charged.

According to online jail records, he was booked in to jail just before 4 p.m.

Authorities say the suspect assaulted the male victim shortly after 11 p.m. Monday at the intersection of N. 5th Street and Hennepin Avenue, near the Warehouse District light rail stop. Security cameras reportedly caught the suspect stomping on the victim's head, knocking him unconscious, and then taking the man's wallet, police said.

The victim, whose age wasn't released, was later taken to Hennepin County Medical Center, where he remained in critical condition on Tuesday morning, according to police.

Anyone with additional information on the attack is asked to contact the homicide detectives handling the case at (612) 673-2881 or (612) 673-3572.
