Correction appended: An earlier version of this story inaccurately reported the date of the assault following the Michigan v. Michigan State football game. It occurred on Oct. 9.

An Ann Arbor police official said in an interview yesterday that authorities believe that two assaults that took place last month are not related.

The first case occurred shortly after midnight on Oct. 15 when an 18-year-old University student was struck on the head with a glass bottle at Fifth Quarter, causing significant injury to his right eye and severe lacerations to his mouth, AAPD Detective David Monroe said. He added that the suspect was described as a college-aged white male with light brown hair that is slightly longer or curly in the back.

Police officials at first suspected that a particular fraternity was involved in the assault, but after a period of investigation, police have not gained any additional information from the earlier leads, Monroe said.

“We had some initial information that maybe fraternity members were involved, but at this point, we’re not certain about it at all,” Monroe said. “It came to a point where wait a second, this could be anyone who was at the bar that night.”

Detective Monroe described a second assault at about 10 p.m. on Oct. 9, following the Michigan football team’s loss to Michigan State. The 22-year-old victim, a Washtenaw Community College student, suffered significant injuries to his teeth and face when struck and kicked by his attacker. The victim reported that the attacker said “Go State” and the victim responded with “Go Blue,” Monroe said. Monroe said the stranger countered with “F*** you” and the victim responded with the same expletive.

Monroe said the suspect was described as 5’8’’ to 6’ with a bald or shaved head, muscular build and was either a white male with darker complexion or a black male with lighter complexion. The attacker’s girlfriend, a white female with curly black hair, threatened to call the police, Monroe said. He added that the police received five different calls about the incident from nearby witnesses.

As of now, Ann Arbor police officials have not released any names of the victims.
