WILLIAMSBURG, Brooklyn — An off-duty officer has been charged with manslaughter after the SUV he was driving jumped the curb and slammed into four people, killing one, in Williamsburg early Saturday morning, police sources said.

The officer, who has been identified as 28-year-old Nicholas Batka, hopped a curb with the vehicle and crashed into the four victims about 3:03 a.m. at N. Eighth Street and Bedford Avenue, sources said.

Batka has been charged with manslaughter, two counts of vehicle manslaughter, three counts of assault, DWI, driving while ability impaired and driving on a sidewalk.

Four people were rushed to the hospital, including a 20-year-old woman. One of the pedestrians who was struck has died, police said. Two are in serious condition, police said.

Witness Kelly Convery said he saw the officer switch from the driver’s seat to the passenger side.

“First he tried to pull out and get away, then he tried to get out of the car, and then he switched sides,” said Convery, who saw the horrific accident from his third floor window.

“It was very apparent he was drunk, and when they took him away, he seemed unresponsive. I don’t know if that was for real or what.”

Other witnesses said they saw Officer Batka flash his badge in an effort to try and get an Uber driver to stop videotaping the scene with his cell phone.

Batka was also taken to a hospital and treated for minor injuries.

Batka was to report to work at 7 a.m. and was assigned to the Manhattan transit task force. He has been on the force for one year.

Batka has been suspended, officials said.
