A woman was arrested in Riverbank on Friday after a Stanislaus County sheriff's deputy said he spotted her hitting her boyfriend with her white station wagon. Sheriff's spokesman deputy Royjindar Singh said he was on his way to the Riverbank police station about 1 p.m. when he saw Roberta Johnston stopped in the westbound lane of Stanislaus Street at a stop sign at Callander Avenue.
Singh was driving an unmarked department vehicle north on Callander and approaching Stanislaus. Singh said he saw Johnston's boyfriend walking in front of her vehicle. Johnston moved forward and her front bumper hit the boyfriend, Singh said. The boyfriend continued to walk south on Callander. Singh said the station wagon turned and Johnston hit her boyfriend a second time at a slow speed.
The boyfriend tried to escape, Singh said, but Johnston followed him and hit him several more times at a slow speed. Singh made a U-turn and noticed Johnston's vehicle had pinned the victim against a chain-link fence. Johnston turned back and started driving east on Stanislaus before Singh caught up with her and pulled her over. Singh got out of his vehicle and asked Johnston to hand over her keys just before a second deputy arrived and detained Johnston.
Johnston, 45, of Riverbank was arrested on suspicion of assault with a deadly weapon other than a firearm. The boyfriend suffered minor injuries but declined treatment at the scene.
