Surveillance video shows the terrifying moment a hooded thief points a gun at a Queens man’s head before beating and robbing him.

The 65-year-old resident was walking to his Floral Park home near 263rd Street and East Williston Avenue around 3 a.m. on April 21 when the gunman followed him inside, police said.

The footage released by cops shows the crook open the front door and walk into the entryway with his gun out — pointing it at the victim’s head.

As the men begin to tussle, the thug throws the resident onto the floor and punches him several times before getting ahold of his wallet.

The thief rushed off in a waiting gray minivan, cops said.

Police describe the wanted man as approximately 25 to 30 years old with a mustache and a goatee.
