Update 10:07 p.m. EST: The robbers apparently dressed as mailmen to get inside the building, the Wall Street Journal wrote. Once they were buzzed up to the eighth floor, one of the robbers, who reportedly was not armed, stood in the hallway as the other demanded jewelry from the safe to be placed inside a bag. The value he left with has not yet been determined, the New York Times wrote.

Police received a 911 call that a robbery was in progress. When they arrived, they discovered the owner was hit in the head with a gun. He was treated for his injuries. There were five employees inside the jewelry store at the time of the heist, but the owner is the only one who was reportedly hurt.

Authorities have a description of the two robbers after they were caught on security camera footage. The gunman was described as black, about 6-foot-4, goateed, about 40 to 50 years old and wearing sunglasses and a black hat. The lookout was described as being black, about 30 to 40 years old, wearing a red baseball cap, with a black zip-up hoodie, black True Religion jeans and black sneakers, the Journal said.

The robbery was described as a rare security breach. 

Original story:

Two armed robbers struck Manhattan’s famed Diamond District near the Veterans Day Parade route Tuesday, NBC News reported. No suspect is in custody after police received a call from a small shop on 47th Street between Fifth and Sixth avenues around 2:30 p.m.

Pedestrians and cars were barred from the street as police searched the eight-story building, the news site wrote. SWAT teams and NYPD's emergency service unit have surrounded the store.

Further details about the apparent crime remain murky, but witnesses told WCBS-AM radio that two armed men ran to the eighth floor of the building where different types of jewelry are sold. One of them had a machine gun and the other had a handgun, Value Walk said. Some sources said the robbery was botched.

No one has been injured, Pz Feed reported.
