A 34-year-old Ann Arbor man was sent to the hospital with a head injury after another man punched him on Saturday during a literary argument, according to police.

Ann Arbor police Lt. Renee Bush said the man went to a party at a home in the 100 block of North Ingalls Street at about 2 p.m. on Saturday. Bush said the man was sitting on the porch with some people he had just met, talking about books and authors.

The 34-year-old man was then approached by another party guest, who started speaking to him in a condescending manner. An argument ensued and the man was suddenly struck in the side of the head, suffering a cut to his left ear, Bush said.

The man’s glasses went flying off of his head and fell to the ground, with one of the lenses popping out of the frames, Bush said.

Police were notified of the incident at 10 a.m. Sunday when they responded to St. Joseph Mercy Hospital Ann Arbor in the 500 block of North Maple Road. The man was being treated for his injuries there, she said.

The incident occurred at about 9 p.m. and the men had been drinking for several hours, Bush said.

The incident still is under investigation.
