A 56-year-old man was hospitalized in critical condition after he was assaulted last week in St. Paul, police said Monday.

Police responded to a possible assault Friday about 9 p.m. in the 800 block of Cleveland Avenue S., said Sgt. Paul Paulos, spokesman for the St. Paul police.

There was a report that a man was seen stumbling in a parking lot. When officers arrived, they found a man on the ground but conscious near a bus stop. He had injuries to his head and was taken to Regions Hospital.

The attack doesn’t appear to be random, Paulos said. No arrests had been made as of Monday morning.

Paulos said police are investigating what led to the man’s injuries.

Authorities didn’t release the man’s identity.
