Police say one victim was walking on the trail around 4:45pm Monday when she was knocked unconscious. She told investigators when she came-to, a young man was attempting to drag her into nearby brush by her ankles. She was able to break free and get away with just a cut to her eyelid, according to police. Three hours earlier in the same area, Redding police say a girl, 17, was grabbed by the buttocks by a teen. In both cases, the attacker is described as a white teen, possibly riding a silver BMX bike. If you have any information, please call Redding police at (530) 225-4200.
