NYPD officers uncovered a cache of 17 guns at a Bronx public housing development — and arrested a 66-year-old man who lived there on multiple weapons charges, police said Thursday. 

Investigators executed a search warrant and found 9mm handguns, 45-caliber pistols and  revolvers at 770 East 165th Street in the Forest Houses around 8:46 a.m. Wednesday, cops said. Two of the weapons had no serial numbers, police sources said.

Deandre Lamar, 66, was arrested and charged with 17 counts of criminal possession of a weapon, criminal possession of a controlled substance, criminal sale of a weapon and possession of a large cap ammunition device, which could be an extended magazine, police said.
