Only a few weeks into the school year and UCLA is searching for a sexual predator who attempted to attack on campus this weekend, cops said.

The suspect tried to grab a female student at Rieber Hall, a residential building on campus, but was thwarted when two witnesses saw the crime and he fled, grabbing the buttocks of a second victim at an adjacent housing complex on his way out, according to a UCLA police statement:

It happened about 2:30 a.m. Friday at 310 De Neve Drive, police said.

The suspect is described as a “light skinned” man in his early 20s, about 5 feet, 10 inches to 6 feet, 1 inch tall, 190 pounds or so, wearing blue jeans and a blue tank top.
