The NYPD Bomb Squad and the FBI are investigating a Queens home containing suspected “bomb making” materials, police sources said.

Authorities said they were tipped off to the potential explosives after the home across from Astoria Park on 19th Street erupted in flames about 2 p.m. Tuesday.

The landlord of the house, who lives on the block, stumbled upon the suspicious packages while surveying the fire damage, sources said. He called the FDNY, who passed along the intel to police, sources said.

Investigators later recovered what was described by police sources as three bags of “bomb making” material, possibly ammonium nitrate. Wick cords, used for fuses, and bomb making books were also found, sources said.

The discovery created a hectic scene with a large police presence and expansive street closures.
