The students are alleged to have used anti-Semitic slurs during the beating on Feb. 15 outside the former Alpha Epsilon Pi, an international Jewish fraternity. The victim was not a Temple student.
Officials from Temple, the district attorney's office and the Philadelphia police department on Monday declined to release additional details about what happened, because the investigation is ongoing.
The victim was seriously hurt in the beating, Temple officials said.
The four students were suspended and school officials said they are awaiting results of the police investigation before deciding whether to expel them.
"Hate crimes will not be tolerated by Temple University," school President Ann Weaver Hart said in a statement issued to students and staff. "All manifestations of intolerance threaten the fabric of our institution and our society."
Alpha Epsilon Pi recently moved to a new fraternity house.
