Two were wounded and one was killed during a shootout Saturday morning in downtown Houston, officials said.

A 27-year-old man who lives at the 2900 block of Pease Street told police he was returning home from a night club about 6 a.m. when he was approached by four or five armed men, according to the Houston Police Department.

The man, who has not been identified, said the group began firing at him, so he drew his own weapon and returned fire.

He was hit one time in his upper back and shot two of the men, one of whom was pronounced dead at the scene, officials said.

The other wounded man was picked up by an unknown person driving a red Chevy Cruze. That man, who has not been identified, was taken to the hospital, where he was charged with aggravated assault with a deadly weapon.

No charges have been filed at this time against the 27-year-old man shot in the upper back.

Houston police are looking for the two or three unknown men involved in the shootout. Police are still trying to determine what led to the shooting.

Anyone with information about this incident is asked to call HPD's Homicide Division at (713) 362-2736 or Crime Stoppers at (713) 322- TIPS.
