HOUSTON -

Two armed men tried to rob a Denny's restaurant, but ended up fleeing after a shootout with a customer.

The shootout happened at a Denny's restaurant in the 11000 block of the East Freeway around 5:50 a.m. Saturday.

Officials said two armed suspects wearing bandannas entered and attempted to rob the restaurant.

The sole customer in the restaurant, a licensed concealed handgun carrier, saw the suspects enter, pulled out his own gun, took cover and fired at the robbers, detectives said.

Investigators said the suspects returned fire and fled the restaurant. The customer followed the suspects, firing as he went. The suspects jumped into a white minivan and fled the scene.

Officials said a white minivan with what appeared to be bullet holes was found later in the 1400 block of Griffen. It had been reported stolen, police said.

So far, police have no suspects in the case.
