The NYPD has put out surveillance video of a robbery involving a shotgun in Queens.

The clip was taken on March 16 outside a home in Ridgewood.

Police say the man with the shotgun demanded the victim hand over his chain.

But the gunman only got away with the victim's jacket.

Police are also looking for a second person who was with the gunman at the time.

Anyone with information on the case should contact the Crime Stoppers hotline at 1-800-577-TIPS, or text CRIMES and then enter TIP577, or visit www.nypdcrimestoppers.com.
