A 29-year-old Ann Arbor man was taken to the hospital and a 36-year-old man who lives near him was arrested after a stabbing Thursday night, police said.
Police are still investigating what started the fight.
"It will reveal itself," said Ann Arbor police Lt. Renee Bush.
The man who was arrested lives in an apartment building near the victim in the 1300 block of Wisteria Drive, where the assault occurred around 8:30 p.m., Bush said.
The two men started fighting outside their apartment buildings, then the fight moved momentarily into one of the buildings before coming back outside again, Bush said.
When the fight had ended, the 29-year-old realized he had been stabbed in the abdomen and leg.
"It was some sharp object," Bush said, though police are still investigating just what kind go weapon was used.
The 28-year-old was transported to the University of Michigan Hospital for treatment. Officers arrested the 36-year-old and took him to the Washtenaw County Jail. He could be charged with felonious assault pending the investigation, which is being conducted by Ann Arbor police detectives.
