A student was bound and robbed in his Cal Poly Pomona dorm room, and police are searching for a gunman, according to the university.
The male victim was able to untie himself and contact his resident advisor around 9:45 p.m. Thursday, university spokeswoman Uyen Mai said. The robbery occurred in the student's first-floor Alamitos Residence Hall room.
"University police investigated the area and swept through the hall and they could not find the described suspect," Mai said Friday. "All the residence halls are locked 24-seven, and you have to have a key to get in."
The Los Angeles County Sheriff's Department assisted in the search.
The attacker was described as a black man in his mid-20s, about 6-feet 2-inches tall, with short hair, and an unshaven face, according to a campus alert. The man is believed to still be armed.
Police released a sketch of the man, pictured below.
Since the incident, the student and his two roommates have been relocated to another room, Mai said.
"We're concerned that it does sound similar to in incident Sunday," Mai said, referring to a robbery near South Campus Drive and Temple Avenue.
Despite two robberies within a week, Mai said the campus is typically "very quiet."
"This is a very unusual type of crime to occur on this campus," Mai said.
Correction: An earlier version of this story implied that the student was found bound in his dorm room. The student was able to free himself and contact his RA.
