A gun-wielding robber stole cash and jewelry — including a man’s gold grill — in a Bronx stick-up, cops said Sunday.

The hold-up happened at 2820 Decatur Ave. near Fordham University around 5:30 p.m. Friday.

One of the victims was contacted by the robber who arranged a personal meeting for unknown reasons, cops said. When the victims arrived at the meeting, the robber pulled his pistol and demanded their belongings. 

He got away with watches, chains, the gold teeth accessory and $2,000 cash. The take was estimated at approximately $4,000.
