In separate incidents late last week, two men were arrested after struggling with BART police officers at East Bay stations, authorities said.

At 6:38 p.m. Friday, police at the Orinda station responded to a report of a man threatening riders aboard a Pittsburg/Bay Point-bound train.

When officers found the man, he tried to walk away from officers before struggling with them, hitting one officer. The man, identified as Patrick Masai, 41, of Oakland, was forcefully detained and taken into custody.

Officers found Masai, who was booked into Martinez county jail on suspicion of resisting arrest and battery on a police officer, also had Oakland police warrants for resisting arrest, driving under the influence and battery on another police officer.

He was held on $20,000 bail Sunday night, according to county records.

At 10:10 a.m. Saturday, officers stopped a man inside the Hayward station on suspicion of fare evasion. After the man gave officers what turned out to be a fake name, he was detained after a brief struggle.

The man, identified as Mark Stewart, 49, of Richmond, was booked into Santa Rita Jail on suspicion of resisting arrest, violating probation and battery on a police officer. Stewart, who also received a BART prohibition order, was not listed in custody Sunday night.
