New video shows the moment a security guard in Santa Ana was hit by a Mercedes SUV during a parking lot robbery.
The incident happened June 4 but the video was released by police on Wednesday.
Investigators said a woman went up to an 83-year-old man and offered to help him with his groceries. That's when police say the woman snatched two gold chains from the man, valued at more than $4,500.
The woman then got into a white Mercedes GLS 450 driven by an accomplice. As they tried to get away, a security guard attempted to intervene but got hit by the vehicle.
The video shows the guard getting knocked down as the SUV took off. Police said he suffered a serious injury to his leg.
Police describe the female suspect as being 5 feet 5 inches, weighing about 140 pounds. Investigators believe she's between 20 and 25 years old and was last seen wearing a gray shirt and blue jeans.
Anyone with information is urged to contact Santa Ana Police Officer Rubalcava at 714-245-8373
