The victim said he was approached by a group of two or three students, and described one of the subject as a Caucasian male approximately 20 years old wearing a dark hooded sweatshirt. That man reportedly displayed a knife and demanded the victim's phone and wallet; the victim, who was uninjured, could not provide a description of the other person or persons involved.
According to Emergency Management, the victim complied and the suspects fled on foot towards the Long Island Rail Road parking lot.
