The student was inside his unit at Villa Alvarado Residence Hall when he heard screaming and yelling outside and opened his front door to investigate about 9:15 p.m. Tuesday, according to San Diego State police. He was immediately struck over the head with a beer bottle, causing a laceration to the top of his head, police said.
The assailant, a white man in his 20s with short blond hair, fled in an unknown direction, police said. He was wearing a white T-shirt and blue jeans.
Anyone with information about the assault was asked to call SDSU police at 619-594-1991.
