SAN JOSE -- San Jose State University police have arrested a suspect in the brutal on-campus beating of a 22-year-old man.
Police say they believe the altercation, between two men who may know each other, was fueled by alcohol.
Kristoffer Bowen, 21, was arrested on suspicion of causing great bodily injury, according to campus police Sgt. John Laws.
The victim was hospitalized with wounds that were not life-threatening after an evening incident Tuesday that ended with him having his head repeatedly bashed into a sidewalk around 8:35 p.m. Campus police previously said that the victim was not a student and had no affiliation with the university.
Police say they believe Bowen was walking with the victim in a group through the campus when the altercation occurred on the sidewalk outside the science building on South Fourth Street.
"None of the people in the group, to our understanding, was involved with university," Laws said.
There was a struggle in the grass on the east side of the science building and at some point the victim had his head slammed into the concrete numerous times, causing "multiple injuries to the victim's face," according to an alert the school issued.
It was the second assault on campus within the last two weeks.
On July 18, a man was sitting on a campus lawn when he was reportedly pistol-whipped and robbed by three female assailants at San Jose State, according to campus police.
The man, who police say was not affiliated with the school, was sitting near the Tommie Smith and John Carlos statues when he was approached by three women. The man was hit in the face and had a backpack and laptop computer taken.
Anyone with information about the crimes is asked to call campus police at 408-924-2222.
