01/29 HEMPSTEAD, N.Y. (UPI) -- Nine persons including four New York City policemen were arraigned Friday in First District Court on charges of assault in the bachelor party beating of a man in a Long Island bar last July 4. The policemen were suspended from the New York police force Thursday when they voluntarily surrendered following action by a grand jury. All of the suspects face up to a year in jail and-or a $1,000 fine on the third-degree assault charges. According to Nassau County District Attorney Dennis Dillon, the men attacked David Shafer, 26, of 11 Sunset Ave., Lynbrook, when he objected to their taking his girl friend's sweatshirt as the couple sat at a table in the "On the Rocks" bar in Island Park. Shafer told police when he tried to get the sweatshirt back about 20 men punched and stomped him inside and outside the bar. Shafer was hospitalized for three breaks in his right leg, nose injuries, several facial cuts requiring stitches and bruises all over his body. After he complained that police called to the scene made no arrests, an investigation was initiated by the Nassau County Police Department and the District Attorney's Major Offense Bureau. The defendants who were members of the New York police force were identified as Detective Thomas Egan, 30, of of 159A Beach 109th St., Rockaway Beach, and Officer John G. Leahy, 26, of 180 Beach 114th St., Rockaway Park, both of the Midtown North precinct in Manhattan; Officer John Bellington, 31, of 108-14 Rockaway Beach Blvd., Belle Harbor, of the 113th precinct in Queens, and Officer Patrick Leahy, 29, of 180 Beach 114th St., of the 68th precinct in Brooklyn. The Leahys are brothers.
