Police are investigating three unrelated assaults along Greek Row at the University of California at Berkeley during the weekend, a police spokeswoman said.
A 25-year-old man was transported for serious injuries after he was assaulted and robbed by four men near Piedmont Avenue and Bancroft Way around 11 p.m. Friday, Officer Jennifer Coats said.
The victim was knocked to the ground and repeatedly hit and kicked, Coats said.
The suspects are described as three Hispanic men and one black man in their early 20s, she said. One of the Hispanic men is about 5 feet 8 inches tall with a medium build and long black hair in a ponytail. He was wearing a white T-shirt and jeans, she said.
In a separate incident a man was attacked by 10 men after refusing to let them into a party in the 2300 block of Piedmont Avenue around 12:30 a.m. Saturday, Coats said.
Officers also responded to a possible fight in progress near Piedmont Avenue and Bancroft Way at 12:56 a.m. Sunday, Coats said.
The 22-year-old man was assaulted by eight to 10 men but declined medical attention, she said.
Police are investigating all three incidents and do not suspect a trend or specific group of people being targeted, Coats said.
Officers advise people to travel with a friend or group of people, walk on well-lit sidewalks and stay alert of their surroundings.
