Two students at California State University at San Marcos are recovering after they were attacked. It happened around 3:15 p.m. on Saturday afternoon.
A student who lives in an on-campus housing facility known as the Quad had a friend visiting when they heard a knock on the door.
The student opened the door and a man forced his way into the room. The man assaulted one person and bit the other. The two victims fought the assailant and he ran away.
The suspect is a white male, approximately 18 years old, with short brown hair, wearing a turquoise shirt, blue jeans and white shoes. Authorities don't know whether or not he is a student. They also don't know how he gained access to student housing.
Margaret Chantung, associate vice president of communications for Cal State San Marcos, says this kind of on-campus attack is rare.
"I have not heard of anything like this happening before," Chantung told KPCC. "The Quad and campus housing is generally very secure and safe. You need to have key access to get into the building."
University officials have issued an alert to students.
They urge them to pay extra attention to their surroundings and be on the lookout for unknown individuals loitering in the area. They also warned students not to let anyone they don't know into the building.
If students see anything suspicious, they should call the University Police Department 760-750 -4567 or call 911 or make an anonymous report to Crime Stoppers at 888-580-8477.
