PINOLE -- Police are renewing their call to be careful when making transactions via Craigslist, after an Oakland man was robbed at gunpoint and his friend stared down a gun in the parking lot of a fast-food restaurant.

The robbery occurred about 9:25 p.m. Sunday after the 20-year-old victim responded to a Craigslist ad from Vacaville regarding car parts for sale, Pinole police Cmdr. Pete Janke said. The victim and the advertiser, who identified himself to the victim as "Arthur," set up a meeting in the parking lot of Wendy's at 1581 Fitzgerald Drive, Janke said.

The suspects escaped in what is described as a gold, four-door Toyota Camry LS but not before a passenger in that car pointed a gun at the victim's friend, Janke said. The Camry LS was manufactured between 1995 and 2000, the front and back windows are tinted, and the California license plate number is similar to 41SF770, Janke said.

The victim, who was driven to the Wendy's by a friend, arrived to find the suspect vehicle in the lot with two people inside of it. When the victim approached, the suspect told him the car part he wanted to buy was in the back seat and to get into the car, Janke said.

When the Oakland man complied, the suspect pointed a rifle at him, Janke said. The victim handed over his cash but refused to hand over his cell phone and tried to get out of the car, Janke said.

The suspect grabbed the man's wrist, but the victim escaped and ran to his friend's car. The two suspects then drove away, Janke said.
