Man arrested in sexual assault at Planned Parenthood, police say

REDWOOD CITY — A 38-year-old man was arrested on suspicion of sexual battery and indecent exposure inside the lobby of a Planned Parenthood on Saturday morning, police said.
Marcelo Arancibia, of Redwood City, was arrested at around 8 a.m. Saturday, after he allegedly entered a Planned Parenthood on El Camino Real. He allegedly grabbed a woman by the buttocks inside the library, then exposed his penis and began masturbating.

Detectives are still investigating the possibility Arancibia has committed similar crimes.
