Three USC students were robbed in separate incidents Monday night. Officials suspect the same people are behind each crime.The first robbery occurred at 9:15 p.m. on the 1100 block of 29th Street. The victim was on his cell phone when he was approached by four suspects who demanded his phone. When the victim refused, a suspect displayed a handgun, and the victim surrendered his cellphone. The suspects left promptly after.The second robbery occurred five minutes later on the 2700 block of Hoover Boulevard. This time, two suspects approached the victim and demanded his property. The victim refused, but a suspect displayed a weapon, grabbed the victim’s property and fled.The third robbery occurred at 9:35 p.m. near the 2700 block of Ellendale Place. The suspect held his weapon out and demanded the victim’s property. The victim quickly complied and the suspects fled.“All three of the victims were USC students and the robberies occurred pretty quickly,” said Dept. of Public Safety Capt. David Carlisle. “We think this is the same group passing through the neighborhood and taking advantage of the people they encounter.”DPS is currently working with the LAPD Southwest division to find the suspects.Carlisle encourages students to take reasonable precautions to prevent more incidents from occurring.“Go in a group if you’re going to be off campus after dark,” Carlisle said. “Don’t go out alone because you’re more vulnerable that way. Better yet, take Campus Cruiser or other university transportation.”Carlisle said he does not suspect the incidents to be gang-related and encourages any students who saw the robberies to contact DPS or LAPD.
