Three alleged gang members were arrested and charged Wednesday over the fatal shooting of a 66-year-old innocent bystander outside his son’s Upper Manhattan deli.

Kelwin Sanchez, 19, Raheam Steed, 22 and 23-year-old Jonadel Lakard were all charged with murder in connection to the May 23 drive-by shooting that claimed the life of Reda Girgis, police said.

The trio of suspects are alleged members of the notorious Trinitarios gang OED, according to sources.

Girgis, who’s from Egypt, was visiting his son and pregnant daughter-in-law in the Big Apple when he was struck in the head by a bullet outside the ChopCheese Deli 2 in Washington Heights, cops and the store manager have said.

The errant shot, believed to have come from a dark gray SUV, was intended for a gang rival, sources told The Post.

Shocking video captured Girgis on the phone outside the deli — next to his pregnant daughter-in-law — when he tumbles to the ground.

A group of teenagers who had been hanging outside the deli are seen scrambling for safety just moments before Girgis falls to the sidewalk — with his son’s wife frantically running into the store a split-second later.

Family friends had told The Post that Girgis’ daughter-in-law gave birth the day after she witnessed his death.

Girgis’ son, Haney Girgis, was not in the store at the time of the shooting, deli manager Gamal Abouelezz has told The Post.

Sanchez, Steed and Lakard — the suspects in the case — were also charged with assault and criminal possession of a weapon.
