The 24-year-old shop assistant was alone in the store when the assailer dressed in a white sweatshirt, dark jeans and a black baseball cap pulled her to the floor saying he was going to kill her.
The saleswoman started kicking and screaming forcing her attacker to flee. Footage of the man was captured on a nearby CCTV camera and will be used as evidence in the case.
The detainee was later released after being charged and is now awaiting trial.
