The victim told police he parked his car in the 200 block of McEvoy Street around 10:40 p.m. He exited the car to go to Fleishman Park and was approached by a group of people who demanded money.
Three of the suspects took the victim's money, cell phone and other personal items, and then began beating him while three others watched, police said.
The six suspects then drove off in two cars, one of which was the victim's, police said. The victim called police from a nearby home.
An officer in San Carlos spotted the stolen vehicle on Holly Street and followed it onto northbound U.S. Highway 101.
Officers from Belmont, San Mateo, Hillsborough, the San Mateo County Sheriff's Office and the California Highway Patrol responded to assist in the pursuit.
Officers attempted to pull the car over on Highway 101, and the suspects exited the highway at Kehoe Avenue and stopped on Norton Street, police said.
The driver was immediately taken into custody, police said. Two men attempting to flee on foot were also apprehended.
The three other suspects, who were in a separate vehicle, apparently followed the stolen car to the same intersection and were also taken into custody.
The six were arrested on suspicion of carjacking, robbery and battery causing serious bodily injury. They are Redwood City residents Joseph Bass, 20, Michael Bass, 23, John Webster, 20 and Kamari Fort, 23; Oakland resident Sean Ward, 20; and San Carlos resident Sarah DiLorenzo, 23.
