DALLAS (CBSDFW.COM) – Dallas Police say they caught a young robber soon after the teen allegedly stole money from the store, Jewelry Galore off E. L. Thornton Fwy.

With his face covered by a mask and wearing a backpack, police say the suspect pulled a large kitchen knife from his clothing and sneaked up behind an employee shortly after 11:00 a.m. Wednesday.

Police say the suspect wrapped his arm around her neck and threatened her with the knife. The suspect attempted to sexually assault the employee but police say she pleaded with him not to and offered him the money in the register.

The suspect said he did not want the money before finally stealing the money and leaving the store.  The woman was not hurt.

Responding officers found the suspect walking with a gun in his hand and he was taken into custody.

The gun turned out to be a BB gun.

A search of his back pack revealed a second BB gun, the large kitchen knife used in the crime, the money  and a roll of duct tape.

The suspect was charged with Aggravated Robbery of a Business and Attempted Sexual Assault.
