He’s no Billy the Kid: Elderly robber allegedly holds up NYC bank — nearly 31 years after last heist

Sherrod Young, 73, is accused of robbing the TD Bank on the Upper East Side.

A septuagenarian armed with a pistol allegedly held up an Upper East Side bank last week — nearly 31 years after his last bank heist.

Authorities identified the suspect as Sherrod Young of Harlem, who was reportedly foiled by modern technology during the March 24 robbery, much to the shock of his family.

“It’s shocking to everybody,” his sister, Sadie Randolph, told The Post. “My brother is 73 years old. It was such a surprise to everyone.”

Young of Harlem was foiled by modern-day technology, authorities said.

Young, who ironically shares his surname with his misdeed, entered a TD Bank around 12:15 p.m. on 3rd Avenue and East 96th Street, donning sunglasses and a mask, and brandishing a loaded .45 caliber Ruger pistol. He demanded cash from the security guard and teller, pointing the gun at them and instructing, “Be quiet. Don’t move! Give me all of the money! Big bills!’’

The teller handed over $1,300, along with a hidden GPS tracker inside the bag.

Authorities used the tracker to apprehend him about a mile from the bank at East 115th Street and Fifth Avenue in Harlem. He was getting back into his red Mercedes Benz C43 sedan approximately 15 minutes after the robbery, according to the federal criminal complaint. The mask was found in his pocket, while the money and the gun were discovered in his car, the complaint alleges.

Young is being held at the Metropolitan Detention Center in Brooklyn.

“He’s not a criminal mastermind,” quipped one police source.

Young’s last bank robbery occurred at a Bronx bank on St. Patrick’s Day 1994, according to the FBI, although specific details were not provided.

He previously pleaded guilty to 15 counts of bank robbery and received a sentence of 18 months to three years in prison, as per the complaint.

Since then, Young had turned his life around, as attested by his sister.

Young was seen on surveillance video in the area of the bank,

“He said that would never happen [again], because I know he loves his kids,” Randolph, 67, said. “He started going to church and everything.”

However, recent behavior changes were noted by his family, with concerns about his mental and physical health.

Young was caught on surveillance entering the bank, wearing the mask.

“He just came out of the hospital not too long ago, with all kinds of tubes in him. He’s not well,” Randolph said.

Young, a retired security guard receiving Social Security, is speculated to have committed the recent heist possibly due to medical bill concerns, given his heart and vision problems.

He is currently held at the Metropolitan Detention Center in Brooklyn.
