HOUSTON -- (KIAH) -- A terrifying scene at a local convenience store was caught on camera behind the cash register.

Customers go about their day at the Todo Market when all of a sudden, armed men dressed in black and wearing masks storm the store and begin firing their weapons.

Store employees dash into a side room, while a customer hits the deck.

The gunmen bang on the door to the "safe" room and then start firing repeatedly into the door.

They also shoot into the bullet-proof glass.

They even shoot the doorknob off, but the door's lock holds.

"The lock is stuck inside," store manager Naeem Sadruddin pointed out. "They didn't have no hangers to remove it."

Fortunately, police say no one was injured, but one customer did have his wallet and cellphone stolen from the counter.
