Dramatic CCTV footage shows at least 10 masked robbers break into a gun store in Houston, Texas, and steal more than 50 weapons.

The attack on Carter's Country gun store happened at around 04:30 local time and lasted just two minutes, police said.

The CCTV footage shows the gang pull off the metal security doors using a chain attached to a pick-up truck.

The robbers then dash in, grabbing weapons from glass cases and racks and stuffing them into bags.
