HOUSTON -

Police are searching for three men who pistol-whipped a store clerk during a violent robbery late Thursday night.

Police said around 9 p.m., three masked men stormed into the Subway-Chevron building with a gun drawn.

Officials said they demanded the three clerks inside the store hand over all of the cash in the register.

Jessica Cordova was working the register.

"He was pointing at me with the gun," Cordova said. "He told me to give him the money. So, I was giving him the money, and I got really nervous, and dropped everything. So that's when he hit me with the gun."

During the robbery Cordova said one of the men threatened her life.

"I was scared, I thought I was going to die," she said. "He kept saying I'm going to shoot you if you don't give me the money so I just gave him the money."

The men got away with cash from the registers, although Cordova was not sure how much money they took.

Cordova suffered minor injuries and did not require medical treatment.

Anyone with information in this case can call 713-222-TIPS.
