A woman walking down a quiet Inner Sunset street got an unpleasant surprise Friday, when she was suddenly mugged by a trio of aggressive miscreants.

The 47-year-old victim was walking near Ninth Avenue and Kirkham Street at 6:31 p.m. Friday when the attack occurred. According to the San Francisco Police Department, a car pulled alongside the victim as she walked, and two "unknown" suspects (no description, including gender, was available at publication time) hopped out of the vehicle and headed toward her.

Police say that the two suspects physically restrained the woman as they robbed her of her cash, her cellphone, her purse, and its contents. When they were done with the theft, they "released [her] causing her to fall to the ground," police say.

The two suspects got back in the car, which was then driven away by a third suspect. The victim was transported to San Francisco General Hospital for treatment of her injuries from the fall, which police say are not life-threatening. As of Monday afternoon, the suspects remain at large, and police say that no arrests have been made in the case.
