An NYPD officer was arrested upstate for having a sexual relationship with a teenaged boy, authorities said.

Rosandre Burgher, 26, an officer with the 46th precinct in the Bronx, was picked up on Tuesday in the Town of Wallkill, a court official said.

“It is alleged that this officer had a relationship with a 16-year-old male, a consensual relationship. This person [the 16-year-old victim] calls directly to Internal Affairs Bureau, makes allegations,” Police Commissioner Ray Kelly said in a press conference today.

“Internal Affairs Bureau goes and meets with Wallkill police department and works in conjunction with them and an arrest was made,” Kelly said.

Burgher was charged with criminal sexual act, unlawfully dealing with a child and endangering the welfare of a child, said a spokeswoman with the Wallkill Court. He was released on $35,000 bond on Wednesday and is due back in court on June 26.

“The officer was suspended,” Kelly said.
