(CBS SF) -- A 13-year-old who said she was nearly kidnapped apparently made up the story, San Ramon Police said Wednesday.

The girl told police a man tried to pull her into his van by her wrist while she was walking in San Ramon on Monday.

Police created a sketch of the man and distributed it to the public Tuesday while conducting an investigation to locate the suspect.

During follow-up interviews with the girl, police said some discrepancies were revealed. Police eventually learned that the report was a hoax.

"We have to investigate these situations fully in order to protect our children and community," police said in a media release Wednesday. "It's unfortunate that a scare in the community was raised by this fabricated incident."
