A Drexel University student was sexually assaulted Wednesday morning by a man Philadelphia police say broke into her off-campus apartment.

The assault happened around 4 a.m. at the victim's West Philly apartment in the 3400 block of Spring Garden.

Drexel police worked with detectives in the Philadelphia police department's Special Victim's Unit to confirm the victim was a 21-year-old female student.

Investigators were not able to say whether the victim knew her attacker.

Drexel's Director of Media Relations, Niki Gianakaris, said the school chose not to alert students about the sex assault because campus police "wasn't notified about the incident until hours after it had already occurred."

Students did get an advisory about another crime this morning. A male student was slashed on campus overnight when he and another student got into a fight over a woman.
