The Prince George’s County police officer whose belt was struck by a bullet during a shootout with a suspect in the Mount Rainier/West Hyattsville area on Saturday was the same man who swore out erroneous charging documents in the infamous incident in which a University of Maryland student was beaten by county police officers after a basketball game, police said Wednesday.

Officer Sean McAleavey, who has worked for the police department for five years and is assigned to the District I station, is one of three officers who fired at the suspect and critically wounded him in Saturday’s incident, police said. McAleavey was in the area investigating a report that someone was banging on the window of a business and throwing bottles at cars when the suspect fired at him, police and law enforcement sources said.

McAleavey was struck in the gun belt and unhurt during the shootout, police and law enforcement sources have said. Dozens of shots were exchanged, and the suspect was hit eight times — but he kept firing even after he fell to the ground, police and law enforcement sources said.

The incident occurred about 8 p.m. at Queens Chapel and Chillum roads, police said.

McAleavey had been suspended in April 2010 after a videotape emerged showing county police officers beating an unarmed University of Maryland student during a raucous celebration after a basketball win over Duke. He had filed charging documents against the student who was beaten, though he was not among those shown in the video, police have said. He was later returned to duty, though the incident remains under investigation by federal authorities, police have said.

Police identified the other two officers who fired as Jorge Martinez, who has worked for the department for five years, and Shane Goudreau, who has worked for the department for four years. Both were assigned to District I. Police have not yet identified the suspect. Cpl. Evan Baxter, a police spokesman, said police had “no expectation” that he would die.

All the officers who fired have been placed on paid administrative leave while internal affairs detectives probe the incident — normal protocol for police involved shootings.
