Accused cop-shooter Robert Williams has been indicted on multiple counts of attempted murder and attempted assault on a police officer, authorities announced Wednesday.

Williams, 45, was arraigned in Bronx Supreme Court on the charges stemming from the shooting rampage that left two cops wounded inside an NYPD van and inside the 41st Precinct in the Bronx last month, police and Bronx prosecutors said.

“This man allegedly attempted not once but twice to assassinate police officers,” Police Commissioner Dermot Shea said in a statement. “The first time uniformed officers helping to keep the Bronx streets safe, the second time officers inside their stationhouse.”

“We condemn these actions and support in every way possible the prosecution by District Attorney Darcel Clark,” Shea said. “We are confident her office will assure that justice is done.”

Williams’ alleged shooting spree began Feb. 8, when police said he walked up to an NYPD van parked on Simpson Street in the Bronx and opened fire, grazing the neck and chin of Police Officer Paul Stroffolino.

Less than 12 hours later, Williams is accused of walking into the 41st Precinct stationhouse and opening fire with a 9mm SIG Sauer pistol, hitting Lt. Jose Gatreaux in the upper arm before running out of ammunition and surrendering.

Neither officer’s injuries were life-threatening.

Williams flashed a smile when he was arraigned on a criminal complaint Feb. 14 — but the cop-hating perp now faces more serious charges after a Bronx grand jury voted the indictment.

He was arraigned on the indictment Wednesday before Bronx Supreme Court Justice George Villegas — and charged with 11 counts of first-degree attempted murder, 12 counts of second-degree attempted murder, 11 counts of attempted aggravated assault upon a police officer or a peace officer, 12 counts of first-degree attempted assault, two counts of second-degree assault, and four counts of second-degree criminal possession of a weapon.

“Fortunately, his mission to kill police officers failed,” Clark said of Williams. “I commend the officers who used tremendous restraint, as well as those who conducted the investigation that led to this indictment.”
