A gunman was fatally shot by an off-duty sheriff’s deputy after opening fire in a Houston nightclub early Monday, authorities said. The shooting left one other person dead and two others injured.

The gunman, who has not been identified, began shooting at approximately 1:21 a.m. local time at Clé, a club where several off-duty Harris County sheriff’s deputies had been working extra jobs as security guards, Houston Police Chief Troy Finner told reporters early Monday morning.

A deputy fired back, Finner said, and Houston police confirmed Monday afternoon after reviewing security footage from inside the club that the deputy had killed the gunman. It remained unclear who had shot the three victims, but police said it was not the deputy.

The two people who were injured were transported to the hospital. One was treated and released with a gunshot wound to the leg, Houston police said Monday afternoon. The other suffered multiple gunshot wounds and is in critical condition.

No deputies were hurt during the exchange of gunfire, Harris County Sheriff Ed Gonzalez tweeted.

In the hours after the shooting, Finner called it a “difficult scene with a lot of moving parts.”

“It’s very difficult because the club was very crowded, dark inside,” he said.
