The student told police she was punched, and her property was taken from her.
The suspects then fled in a white sedan. Police say no weapon were displayed but a gun was mentioned.
The victim was taken to a local area hospital for non-life-threatening injury.
Investigators say the vehicle drove across Baltimore Avenue and traveled east on College Avenue. They are reviewing security cameras in the area.
