Police released a video of the violent jewelry store heist in Brooklyn yesterday that left the shop’s owner with a gunshot wound to the chest.

The video shows the armed punk pulling his gun out of his waistband while walking right up to his victim, Reggie Sanocki, 54, in the well coordinated stickup of Studio Jewelry in Greenpoint. He then chased the jeweler to the back of the store at gun point, police said.

The sticky-fingered accomplice, who was playing lookout, slid over the display case and emptied its contents into a bag.

Sanocki was shot once to the chest during the robbery and taken to Bellevue Hospital, where he is in stable condition, cops said.

The two thugs fled from the store down Nassau Avenue. They are described as being 35 to 45-years-old and around six feet tall.
