PHILADELPHIA—Police say they've arrested two suspects and are still seeking a third after a home invasion in which four Temple University students were bound and robbed at an off-campus apartment earlier this week.

Investigators say they brought the men in for questioning Tuesday, hours after the release of surveillance photos. They were charged Wednesday, but their names weren't immediately released.

The robbery happened shortly before 7:30 p.m. Monday at a residence not far from the school's north Philadelphia campus. Police say the three suspects followed a female student home to her second-floor apartment.

Investigators say the men forced their way inside and duct-taped the woman and her three roommates before taking off with computer equipment, cell phones, credit cards and an unknown amount of cash.

The victims weren't hurt.
