A petite Texas 17-year-old girl staged the gunpoint carjacking of a friend by two other friends, police said.

At first, authorities said they believed Susan Mize, of Spring, was also a victim. She was arrested after deputies with the Montgomery County Sheriff's Office conducted an investigation and quizzed her about what happened.

"During the course of the investigation … deputies learned that Susan had lied about the entire incident,"Lt. Scott Spencer Spencer said.

He said deputies learned that Susan had set up her friend Preston Barry, 20, also of Spring, to be robbed by two juvenile males. They arrested one of the juveniles, a 16-year-old boy, and issued an arrrest warrant for the other, a 15-year-old boy.
