A federal agent assigned to help protect dignitaries at the UN General Assembly was arrested yesterday after a run-in at a trendy Times Square hotel.

Police officers were dispatched at about 6 a.m. to the Paramount Hotel on West 46th Street in response to a report that a drunken guest pulled a pistol on a guard.

Jeff Parke, 33, was arraigned in a Manhattan court on a misdemeanor charge of menacing, and was released without bail.

Homeland Security officials in Washington said only that an Immigration and Customs Enforcement agent on assignment in New York had been accused of wrongdoing and placed on leave.
