It was around 11:00 a.m. on Tuesday when police were called out to the corner of 31st and Federal for an assault.
Once there they found a man who was unresponsive. He was taken to Cooper University Hospital.
The man had no identification on him, but police describe him as being in his 30s and he appears to be Latino.
Officials suspect the assailants are juveniles and they are trying to see if cameras at the nearby Woodrow Wilson High School or any other cameras in the area got images of the assault.
The victim has not yet been identified.
