Antioch police have arrested four people allegedly involved in a Friday afternoon stabbing that appears to be gang-related. Police said the exchange began at about 1:45 p.m. Two men aged 18 and 20, both Antioch residents, were walking south on Hillcrest Avenue near state Highway 4 when four people approached them in a red Oldsmobile Cutlass. The two groups exchanged word and hand gestures, according to police, and four people got out of the Oldsmobile and chased the two men on foot. They caught up with the pair at a nearby Jack in the Box restaurant, and all four suspects brandished knives, according to police. One of the two victims was stabbed in the stomach and hit over the head with a bottle during the ensuing assault, according to police. He was transferred to a nearby hospital and treated for his injuries. Officers responding to the scene arrested all four people and located multiple knives. Police arrested Roberto Martinez and Buddy Robinson, both 19, as well as two juveniles, age 15 and 16. All four are Antioch residents. The incident is still under investigation, and appears to be gang-related, according to police.
