Atherton police say a girl out for a run early Saturday afternoon on McCormick Lane was grabbed by a man who tried to rob her, but she was able to break free and run home.
Police said the man ran up behind the 17-year-old Atherton resident at about 12:15 p.m., grabbed her, and demanded her cell phone.
Police describe the suspect as a short and stocky Hispanic male, 30 to 40 years old, with brown eyes, no facial hair and bald, and wearing dark pants.
Police said they believe the man was driving a copper-colored or red-brown small truck, possibly a Chevrolet or a Ford. They said the man may have had a weapon such as a knife, but that the girl did not get a good look at a weapon.
Anyone with information on the incident, or who might have seen the suspect or suspect's vehicle, is asked to call the Atherton Police Department at 650-688-6500.
