The Prince George’s County Police Department is investigating an incident in which an unidentified man allegedly assaulted and inappropriately touched a female student Sunday morning, police said.

The student reported the incident, which occurred between midnight and 1:30 a.m. Sunday, at about 9:40 p.m. Sunday, department spokesman Cpl. Nate Lewis said.

The incident took place during a gathering at the 4300 block of Knox Road when the suspect reportedly closed himself in a room with the student, according to a safety alert from University Police on Monday afternoon.

The suspect allegedly proceeded to put his hand over the student’s mouth, telling her to remain quiet. The student reportedly bit the suspect’s hand and the suspect responded by continually slapping the student in the face. The suspect held her down and groped over her personal parts, according to the alert.

The altercation ended when someone attempting to enter the room startled the suspect, and the student ran out of the room and returned to her residence, according to the alert.

No injuries were reported from the incident, Lewis said.

The department is conducting an investigation and asks that anyone with information on the incident call 301-772-4908.
