Two robbers punched a man in East Harlem before stealing thousands in cash and his gold chain in broad daylight, police said.
Cops released photos of the men suspected of attacking the victim on Dec. 30 at around 2:30 p.m. in front of an apartment building on East 109th Street.
One of the assailants grabbed the 30-year-old victim from behind while the other took a swing, punching the unsuspecting man.
As the victim reeled from the strike, one of the robbers grabbed an envelope that held $5,000 inside and snatched a gold chain with a diamond cross hanging from the victim's neck.
The robbers, both described as black men, then ran off eastbound on 109th Street before turning north on Second Avenue.
Investigators said one of the attackers stood at 5 feet, 8 inches tall and wore a black jacket, blue jeans and a green knit hat.
The second suspect was about the same height and sported a mustache. He was last seen wearing a black leather jacket, dark hooded sweater and dark boots.
The victim didn't need any medical attention, police said.
NYPD asks that anyone with information on the robbery or suspects call Crime Stoppers at 1(800) 577-TIPS (8477), or text their tips to CRIMES (274637), then enter TIP577.
