An off-duty New York City police officer was found dead Saturday afternoon of a suspected self-inflicted gunshot wound, a department spokesperson confirmed to Fox News.

The officer’s colleagues found him dead in his Staten Island home around 2 p.m., law enforcement sources said. They were concerned when he didn’t show up for work and had gone to check on him.

No additional information was released by the NYPD. The NYPD Sergeants Benevolent Association tweeted that the officer was a sergeant, but did not give any other details

The officer is the fifth member of the NYPD to commit suicide since early June.

New York Police Commissioner James O’Neill last month said the department had a “crisis” on its hands after three officers took their own lives over a 10-day period.

“Cops spend so much of their days assisting others. But before we can help the people we serve, it is imperative that we first help ourselves,” O’Neill said at the time. “Accepting help is never a sign of weakness — in fact, it’s a sign of great strength.”
