Police in Palo Alto arrested a massage therapist accused of attacking four women during separate appointments.
Officers said Rajesh Vashisht turned himself in on Wednesday.
Police charged him with misdemeanor sexual battery.
According to detectives, the 35-year-old man attacked a woman last year when he worked at the La Bell Day Spa on El Camino Real.

Police said he did not work at the salon by the time the last three investigations were revealed.
