SAN DIMAS — Police said an armed man thumped a car with his hand to get a driver’s attention then robbed him of money and jewelry Wednesday.

The 2:45 p.m robbery occurred on Arrow Highway and Valley Center Avenue.

Glendora police Lt. Joe Ward said a 62-year-old Anaheim man was pulling over to answer his cell phone. As he was trying to park between two vehicles, Ward said the man heard a loud thump in front of his car.

The driver saw a man with a gun who demanded money.

In addition to the cash, Ward said the robber also took some jewelry.

A silver van then pulled up. Ward said the robber jumped into the van which left.

The suspect was described as a Latino in his 20s with short dark hair. He wore a black shirt.

Ward said Glendora police took a courtesy report for the sheriff’s San Dimas station which is handling the robbery.
