The 17-year-old girl was walking on the Grinnell Pathway near the Life Sciences Addition building at about 10:45 p.m. when she noticed a man following her, UC Berkeley police spokesman Lt. Alex Yao said.
After crossing the west Grinnell Bridge, the girl saw the man exposing himself, Yao said.
She tried to run away but the man grabbed her shoulder and began touching her inappropriately, according to police.
When the victim screamed, several people came to her aid and she was able to run away, Yao said.
The victim called UC Berkeley police from a nearby phone, but police were unable to locate the suspect, Yao said.
The student was not injured, Yao said.
“These criminal acts are serious and dangerous,” Yao said.
The suspect is described as a black man in his early 20s who is about 5 feet 10 inches tall, weighs 165 pounds, with a skinny to medium build, police said.
He was last seen wearing a red wide-brimmed baseball cap with a white emblem, a black puffy jacket and jeans, according to police.
Campus police are working with Berkeley police to investigate the attack and determine whether it is connected to other recent attacks, Yao said.
Anyone with information about this attack is asked to contact UC Berkley police (510) 642-0472.
