A lieutenant with the New York Police Department was arrested on suspicion of sexually battering a woman at an event they were both attending in Long Beach Saturday night, according to authorities.

Police arrested Jonathan Simons, 35, early Sunday morning at a local hospital where he’d been taken after getting into a fight with another guest at the event, Long Beach Police Department spokesman Ben Hearst said.

The guest had taken the situation into his own hands and injured Simons after apparently being told about the woman’s allegations, according to Hearst.

That altercation is what originally prompted police to respond to The Grand Long Beach events center at Willow Street and Grand Avenue around 11 p.m.

When officers got there, a woman told them Simons had sexually battered her and she wanted to pursue charges, Hearst said.

Hearst declined to say exactly what the woman alleged Simons did. The case is still under investigation, he said.

Simons is a lieutenant with the NYPD who works in personnel, according to the department. He’s currently suspended, the NYPD said Tuesday.

Hearst said he did not know what type of event Simons was attending. The Grand Long Beach hosted several weddings and two birthday parties that day, according to event center staff.

After taking Simons into custody at the hospital, officers booked him on suspicion of misdemeanor sexual battery and released him on $20,000 bail Sunday morning, according to jail records.
