Suspect in uptown slay busted in Del.

The suspect in the fatal shooting of an Uber Eats deliveryman during a botched robbery in East Harlem has been arrested in Delaware after more than two months on the lam, officials said Wednesday.

Mitchell Thompson, 25, is facing murder charges for allegedly gunning down 32-year-old Mamadou Diallo outside a Burger King at E. 125th St. and Third Ave. on May 20.

Thompson was ordered held without bail during a brief arraignment in Manhattan Criminal Court after he was hauled back to New York on Tuesday. He’s due back in court Sept.

4.

“They just said they caught him,” Diallo’s relieved sister Kadiatou Diallo told the Daily News on Wednesday after talking to police. “We’re waiting for the court date.”

The family is reeling from the loss.

“We still can’t believe everything,” the sister, 36, said. “It’s terrible.”

Detectives identified Thompson as Diallo’s killer early in the investigation, officials said. On June 10, a Manhattan Criminal Court judge ordered a warrant for his arrest after police learned he had fled the state, according to court documents.

Diallo (inset) was waiting for a bus on 125th St. after finishing his shift for Uber Eats at 2:30 a.m. when Thompson tried to rob him, according to police.

The deliveryman tried to run away from Thompson but was shot in the back, officials said. Medics rushed Diallo to Harlem Hospital, where he died.

Diallo’s relatives said the city’s overnight subway shutdown during the coronavirus pandemic is partly to blame for his death. The hardworking immigrant usually took the train home, but the subway shutdown forced him to take a roundabout bus trip — leading to his fatal confrontation with Thompson, his grieving family said. “The last train is at 1 o’clock, he missed it and he took the bus,” Kadiatou Diallo told the Daily News after his slaying. “He would be on the train. He would never go that route.”
