The man was walking near his home in the 3200 block of Vineyard Avenue around 11:30 p.m. when a car pulled up and a passenger asked for directions, the report said.
When the man approached the car, the passenger told the him he had a gun and demanded money. No gun was seen, but the pedestrian handed over his wallet, with an undisclosed amount of cash.
The car was last seen traveling eastbound on Vineyard Avenue, possibly headed toward Livermore, the report said. It's described as an early 1990s two-door compact, dark in color, possibly a Toyota Camry or Honda Accord. It had manual transmission and a loud exhaust, and sounded, according to the report, like it had a hole in its muffler.
The victim didn't get a clear view of the driver, who is described only as a white male, but the passenger is described as a white male, 25-to 35 years old, a large build and a beer belly. He was unshaven and wearing a dark blue beanie-style cap with an orange stripe. Anyone with information is asked to call Pleasanton Detective Eric Fredgren at 931-5100.
