A freelance photographer for The New York Times was arrested on Saturday night while on assignment with two reporters who were conducting street interviews in the Bronx.

The photographer, Robert Stolarik, 43, who has worked regularly for The Times for more than a decade, was charged with obstructing government administration and with resisting arrest. He was taking photographs of a brewing street fight at McClellan Street and Sheridan Avenue in the Concourse neighborhood.

Mr. Stolarik was taking photographs of the arrest of a teenage girl about 10:30 p.m., when a police officer instructed him to stop doing so. Mr. Stolarik said he identified himself as a journalist for The Times and continued taking pictures. A second officer appeared, grabbed his camera and “slammed” it into his face, he said.

Mr. Stolarik said he asked for the officers’ badge numbers, and the officers then took his cameras and dragged him to the ground; he said that he was kicked in the back and that he received scrapes and bruises to his arms, legs and face.
