BRISTOW, Okla. (KFOR) – Authorities say a Bristow city employee is behind bars after being accused of sexual assault.

Investigators say they began looking into the case in September after a woman came forward and told officers that she had been sexually abused by 49-year-old John Olson.

After investigating the claims, agents with the Oklahoma State Bureau of Investigation arrested Olson at Bristow City Hall, where he worked as a city employee.
