An armed Texas couple got into a shootout with two would-be robbers at a gas station Tuesday, wounding one of the suspects, according to police.

The chaos erupted after a woman saw two men get out of separate cars with guns in the parking lot of the gas station in north Houston around 5:30 p.m., police told Fox 26.

The woman, who was armed, called her husband, who was also packing heat, to alert him of the danger while he was inside the store, cops said.

While the two suspects were trying to rob the place, one of the men threatened to kill the husband and hit him with a pistol and a gunfight broke out, police said. 

One of the suspects was shot multiple times and the other fled in a green Dodge Charger.

Neither the husband or wife were injured.

When police arrived at the scene, they found the couple, who had called 911, holding the wounded suspect at gunpoint.

Mario Ipina Duque was shot several times by the man and woman. He is currently hospitalized in police custody.

The suspect, identified as 39-year-old Mario Ipina Duque, was treated at the scene by Houston Fire Department paramedics and taken to a local hospital.

The husband and wife were detained at the scene and their weapons were recovered.

Investigators determined that they shot Duque in self-defense. 

Duque remains hospitalized in custody of the Houston Police Department. He was charged with aggravated assault with a deadly weapon and unlawful carrying of a weapon.
