A Foothill High teen is missing and police are asking for help locating her.
Danielle Hammer, 15, went missing Saturday night after leaving her home at about 6 p.m. "with unknown friends," a police report said.
The girl's parents don't know where she was headed, and she has not returned home or called since.
"We've assigned a detective to it," said Pleasanton police Sgt. Kurt Schlehuber. "We're following up on every lead we get."
Hammer is white, about 5 feet 5 inches tall and around 120 pounds, with brown hair and brown eyes. She was last seen wearing blue jeans and a gray hooded sweatshirt with "California Republic" on the front.
Anyone with information on her location is asked to call the Pleasanton Police Department at 931-5100.
