CHAMPAIGN — Police say alcohol was a factor in an attack on a University of Illinois student whose head was bashed on concrete pavement early Thursday on campus.

Andrew E. Brewer, 20, of Mahomet, was charged Thursday with aggravated battery and remained in the county jail Friday in lieu of $150,000 bond.

Meantime, a Carle Foundation Hospital spokeswoman said the victim had been released from the hospital.

University of Illinois police Lt. Roy Acree said about 2:20 a.m. Thursday, police were told of one man chasing another. Witnesses saw a man, later identified as Brewer, pick up a 19-year-old man in the 800 block of South Oak Street and "pile-drive" him into the ground.

"That usually means some type of head-first landing," Acree said.

The witnesses saw the assailant head west over the railroad tracks toward Neil Street. Police found Brewer in the 600 block of South Neil Street and arrested him after witnesses identified him as the man who attacked the other man, a UI student.

Tests done at Carle Hospital showed the victim, from Orland Park, had a blood-alcohol content of 0.267 percent, Acree said. That's more than three times the amount for a driver to be presumed intoxicated in Illinois.

"We are still looking into where and why this altercation even took place. We're looking at some locations both of them may have been. We believe both of them had been drinking," Acree said.

Acree said he wasn't certain of the injuries to the Orland Park teen but was told it involved trauma to his skull. Investigators were unable to speak to him Thursday because of his condition, he said.

State's Attorney Julia Rietz confirmed that Brewer, a former standout athlete at Mahomet-Seymour High School, was given court supervision as a juvenile in 2008 for criminal damage to property for throwing bags of ice off an Interstate 74 overpass near Mahomet on passing vehicles.

Acree said on Friday that his department had received numerous reports from housing officials in the previous two days.

"The activity has definitely picked up for us, especially in the dorms," Acree said. "We're dealing with everything from a suicide attempt to cannabis possession to alcohol incapacitation."

Thursday was move-in day for the dormitories although early move-in was allowed Tuesday.

Acree said students away from their parents for the first time can be naive and when alcohol abuse gets added in, the consequences can be severe.

"If students choose to drink they need to be responsible and pay attention to what's going on around them. Sometimes, it's the first time away from home without any supervision from their parents. We have resident directors and resident advisers in the dorms, but they can't possibly be everywhere at the same time," he said.

"Students need to realize that even though this isn't Chicago or a large metropolitan area, we do have crime that takes place here on campus," he said.

He advised students to pay attention to their surroundings, avoid texting and talking while walking, take the MTD bus, a cab or SafeRides. For those who have to walk, have a friend with you, especially after drinking.

"If you feel like somebody is following you, try to find the nearest business, dorm or apartment with a light on and call the police. With 40,000 students, it's hard to get it through their heads what we're trying to talk about. Nobody ever believes he's going to be a victim of a crime until it's too late," Acree said.
