The gangbanger arrested last month in California for the shocking 2019 stray bullet killing of 14-year-old Aamir Griffin on a Queens basketball court is on his way to face a New York City judge.

Sean Brown, 18, was escorted by cops out of the 113th Precinct Saturday evening, and was on his way to Queens Supreme Court for his arraignment, which is expected Tuesday. 

Brown wore ripped black skinny jeans, a black sweatshirt and yellow sneakers as he exited the precinct. His mouth covered with a blue mask, he mumbled but did not clearly respond to reporters’ questions as two detectives deposited him into the back of an unmarked car to take him to court.

Brown, who lived in Jamaica, Queens, before hightailing it to California, will be charged with one count of murder, law enforcement sources said.

Brown — who sources said is an alleged member of the Money World gang — was busted Aug. 23 by Los Angeles County sheriff’s deputies on a warrant for killing Griffin. He was extradited to New York on Friday.

“I just watched him grow up from a baby,” said a former neighbor of Brown’s, who would not give his name. He said Brown’s family has since moved away.

Law enforcement sources said Brown is a person of interest in two other shootings in Jamaica — from Oct. 11, 2019 and July 6, 2020.

He was also injured in a shooting on New Year’s Eve last year, sources added. Brown was sitting in a car on 154th Street in Jamaica when another car pulled up and six shots were blasted, striking him in the shoulder. Two people were busted on attempted murder and other charges in that shooting — Donta Kennedy, 20, and Marqiece Smith, 22.

Griffin was a promising basketball player and a freshman at Benjamin Cardozo HS, who was shooting hoops at Baisley Park Houses on Foch Boulevard in Jamaica when he was shot on Oct. 26, 2019.

The fatal bullet was fired from more than 100 yards away. Detectives immediately suspected the shooting was gang-related and that Aamir was not the intended target.

Aamir’s mom Shanequa Griffin, 39, told The Post police told her Brown was back in the city to face justice.

“They told me everything,” she said. “It’s good.”

Last week, the grieving mom said she was excited Brown had been caught. “He took a lot from me. He broke my heart,” she told the Post. “I just want him to know that he is going to get what he deserves.”

“Honestly, I cry a lot still. It’s still fresh for me. Every day is still like it just happened like it was just yesterday,” she said.

Griffen had a “Magic Johnson smile” and had already attracted attention from college scouts for his prowess on the court, his coach at Cardozo, Ron Naclerio, said.

Friends and family described the boy as a “really good kid” and “innocent.”

The case rocked the victim’s South Jamaica community and prompted a wide search for the shooter. Police offered a $10,000 reward for help bringing the boy’s killer.
