A San Francisco resident was assaulted this past Wednesday morning while jogging along O'Shaughnessy Boulevard. According to Captain O'Leary's daily email:

A local resident was bitten on her lower back by a man as she jogged on O'Shaughnessy Boulevard. She felt pain as she ran and saw that a man she had just passed was restraining her. A witness saw the woman run pass the suspect (described as a white male 18 to 24 years of age, standing 5'8" tall, weighing 150 pounds, with brown hair, wearing a blue and white checkered shirt, blue jeans and black and white checkered shoes) and then saw the suspect run toward the victim, crouch, and press his face to her back. The suspect fled south on O'Shaughnessy Boulevard. Glen Park Canyon was searched to no avail.

The SFPD Sex Crimes Unit then took over the case. No arrests have been made. Of course. So, you know, be careful while jogging, ladies. Or, really, just start carrying a cute, pearl-handled pistol pepperspray while you get your daily exercise.
