The robbery happened around 7:15 p.m. at Marina West Park on the 1300 block of El Portal Way. Julian Lopez, 34, told police he had just locked the bathrooms to the park when he was confronted by about 10 male suspects.
Eight of them had bandanas covering the bottom portion of their faces. Two other suspects threatened and assaulted Lopez while holding knives. They were able to get the victim's wallet. Before fleeing the scene, the suspects took items from Lopez's city work truck and vandalized the tires.
The suspects, only described as Hispanic males between 15 to 18 years old, were last seen heading towards Novato Drive. Anyone with information was asked to contact the Oxnard Police Department at (805) 385-7796.
