The University of Houston police are working to determine if two recent robberies are related.
The latest occurred on Wednesday at around 3:30 p.m. A safety alert was sent out to students to warn them about the robbery.
Police said the latest victim was getting something out of his car when two men in a dark-colored car pulled up. The student told police a man with short dreadlocks got out of a vehicle, pulled out a gun and robbed him before taking off.
A similar robbery happened on Sunday afternoon on Holman Street, across from a campus police station. Police said the student was walking when two men drove up, pulled a gun and robbed the student.
Neither student was injured.
Students said they're worried about their safety.
"Whenever I go back to my car and I'm by myself, I'm scared because I know I could be the next one," student Sara Padilla said.
"It's creepy," student Julia Dugat said. "I try to walk with somebody to my car. Other than that, there's nothing else I can do."
University officials said security has been increased. It is utilizing its 50 police officers, 1,000 security cameras around campus and at least three kiosks staffed by security officers.
"Our goal is always to reduce crime and keep students safe in an environment conducive to learning," Lt. Brent Collier said.
So far, no arrests have been made.
