A Chico man is in custody and charged with sexual assault after an incident Friday night.
Police responded to the report of a sexual assault just after 8 p.m. in an alleyway on the 1300 Block of Laburnum Avenue.
Officers arrived in the area to find 30-year-old Claudio Sanches fleeing.
They quickly detained Sanches and subsequently arrested him without further incident.
Police say they believe the attack was random.
"The victim's activities prior to this assault were everyday activities. There was nothing out of the ordinary," officer Todd Lefkowitz said.
Lefkowitz also wants to warn people to stay alert when out alone.
"Be very aware of who's around you and what avenues you have to go if someone were to approach you, you know, what escape routes you have and what measures you can do to protect yourself."
Sanches was transported to the Butte County Jail on multiple charges including sexual assault.
The investigation is ongoing.
