Ann Arbor police said today that two men were assaulted early Sunday by a group of men in the Fourth and William parking structure roughly 90 minutes after a man was arrested in the same structure for allegedly hitting a woman with a belt.

Police continue to investigate the 3:10 a.m. assault on the men, ages 24 and 25. The 25-year-old man said he suffered a fractured wrist and torn rotator cuff after being hit with a tire iron.

The 24-year-old man, whom Ann Arbor.com is not identifying because he fears retaliation, said that he was in his car, along with his girlfriend and 25-year-old cousin, waiting in a line of cars to exit the garage. After he declined to let a car pull in front of him, a couple of men got out of the car and whistled for their friends, he said.

The 24-year-old man and his cousin then got out of their car and were confronted by at least a dozen men, some of whom had belts in their hands, he said. At least one had a tire iron. The 24-year-old said the men hit him and his cousin repeatedly with the belts. His cousin was hit with the tire iron, suffering a fractured wrist and torn rotator cuff. At one point, one of the men in the group threatened to get a gun, he said.

The 24-year-old said things then settled down and he got back into his car. As he continued to wait in a line of cars to leave the garage, the men surrounded his car, hitting it with belts and punching and kicking it, he said.

The 24-year-old man was in such fear that he drove as quickly as possible around other cars in order to get out of the garage, striking a car, he said. He called police once he drove away from the garage. His car had more than $11,000 in damage.

Ann Arbor police spokeswoman Lt. Renee Bush said investigators didn't learn until Monday that one of the men suffered a fractured wrist.

The assault wasn't the only incident in the garage early Sunday. Ninety minutes earlier, police arrested 21-year-old Willie Peavy of Dayton, Ohio, who they said struck a woman in the back with a belt in the garage. Police used pepper spray on Peavy after he allegedly refused to drop the belt. He was charged with assault with a dangerous weapon.
