A male subject was yelling and causing a disturbance on a Richmond train. Officers arrived and detained the subject (Ismael Williams, 25 years old, Modesto) on the platform. Williams attempted to leave the detention prior to its conclusion and board the train. A records check revealed an outstanding $2500 warrant for theft. Williams was arrested for the warrant and for resting/delaying a police officer. Williams was booked at the Fremont Jail.
