The two cohorts, both 21, are considered armed and dangerous, Walker said. The victim positively identified Harris and Phillip as the assailants from a photo spread, and arrest warrants were issued for the pair on Saturday, he added.
Investigators have already charged a third man who participated in the robbery, Walker said. Devon Bond, 21, also attends Drexel helped set up the heist, Walker said.
Bond, Harris and Phillip all live at University Crossings, an off-campus student housing property at 31st Street and John F. Kennedy Boulevard.
Bruiser Flint, the head coach of Drexel's basketball team, said last night that he was unaware that two of his players were wanted by police. "I'm trying to figure this thing out," he said.
Other Drexel officials could not be reached for comment.
The trouble started shortly before 10 p.m. Wednesday, when a surveillance camera recorded Bond, who was wearing a backpack, trying to open the door to a young woman's apartment on Lancaster Avenue near 36th Street, Walker said.
Bond paced back and forth for a little while, with a cell phone pressed against his ear. He bided his time in a nearby business, and then returned to the apartment at 10:30 p.m.
This time, he rang the doorbell, and the woman answered. Walker said that the woman recognized Bond from Drexel - they both took the same business class - and as a friend of her male roommate, who wasn't at home.
She invited him in, and the plan started to kick into gear. As Bond entered the apartment, he was shown on surveillance footage sticking a piece of paper between the door frame and the lock, preventing the door from locking, Walker said.
Bond and the female student made small talk for a few minutes, and then he announced that he was leaving.
