A station agent reported that a subject fare evaded out and started cussing and yelling at her. The officers arrived and contacted the suspect (Joseph Wade W/M). A warrant check revealed Wade had a $20,000 felony warrant out for his arrest for drug possession. The subject was booked for the warrant via an out of county waiver at the San Francisco County Jail. The fare evasion could not be substantiated and no citizens’ arrest was made for disturbing others.
