The Mastic Beach man charged with shooting a Suffolk police officer has been indicted, and will be arraigned on the grand jury charges in Suffolk County Court in Riverhead on Friday, records show.

Sheldon Leftenant, 22, faces charges of attempted aggravated murder and resisting arrest, the same charges originally levied against him after his arrest early Thursday morning, records show.

Leftenant is accused of shooting Second Precinct Officer Mark Collins in the neck and hip just before midnight on March 11 after a traffic stop in Huntington Station. Collins, 35, was in an unmarked car with two colleagues from the gang unit when they stopped a vehicle that was speeding and swerving through traffic near East Jericho Turnpike and Mercer Court.

Leftenant, one of four people in the car, bolted from the backseat and took off running onto Mercer Court, a residential street, and Collins and Officer Damian Torres gave chase, prosecutors said.

Collins and the other officers recognized Leftenant and two others in the car as members of a local gang known as The Tip Top Boyz, prosecutors said.

Collins tried to arrest Leftenant on Mercer Court, and Leftenant fired four times at Collins, hitting him twice, according to police and prosecutors. After the shooting, Collins, who was bleeding profusely but still alert, told Torres: "Sheldon Leftenant shot me," police said.

Leftenant told authorities he ran from the car to avoid being caught with a gun, police said. He pleaded not guilty at his initial arraignment last Thursday. He is being held without bail, and faces 40 years to life in prison if convicted, prosecutors have said.

He will appear Friday before State Supreme Court Justice John Collins.

Collins, a 12-year veteran of the force, was released from Stony Brook University Hospital on Sunday.
