Three men allegedly stole some $700 in cash from a Manteca motorist gassing up at the Chevron gas station at Yosemite and Spreckels avenues about 4 p.m. Thursday with two of them reportedly attacking him while the third made off with his wallet and cash from the front seat of his car. The victim said the money was from his girlfriend’s paycheck that the trio found in his car. The driver in his mid-20s said the men drove off as he called police.
