Internal Affairs to Investigate Stabbing of Off-Duty Officer The New York Police Department has opened an internal affairs investigation into a police officer who reported that he had been stabbed by an intruder on Wednesday, Paul J. Browne, the department's chief spokesman said. The move seemed to cast doubt on the officer's story. The officer, Rishi Gobin, 34, who is assigned to the 42nd Precinct in the Bronx and has served in the department for about five years, said an intruder assaulted him in his home, but the motive of the attack and whether anything had been stolen were unclear. Mr. Gobin was taken to Jamaica Hospital Medical Center for treatment for a stab wound in his right side. He has since been released. Though Mr. Browne did not say what was being looked into, a law enforcement official, who declined to be named because the investigation was continuing, called the case "problematic" and said investigators were examining, among other things, whether the wounds might have been self-inflicted. "It's kind of bizarre," the law enforcement official said. We're still sorting it out. Mr. Browne said there was "nothing I know to suggest that he stabbed himself." After he was wounded on Wednesday, Mr. Gobin called 911. But because he dipped in and out of consciousness at the hospital, investigators were unable to get a clear picture of what occurred, Mr. Browne said on Wednesday. Footage from surveillance cameras on neighboring houses on 170th Street, near Liberty Avenue, does not show anyone entering or running out of Mr. Gobin's house, the official said. The department's crime scene unit was at the house on Thursday. Mr. Gobin had been "upset over marital problems," the official said. Calls to Mr. Gobin and his immediate family were not returned.
