At about 1:45 a.m., police received a report of an incident involving a man and woman near a dark-colored 1970s Buick by the intersection of Moller Ranch Drive and Foothill Road. Officers responded but did not find the vehicle or either person.
About five minutes later, police received a report of a gray vehicle driving recklessly in the parking lot of Foothill High School.
Five minutes after receiving the second report, officers spotted a vehicle matching that description driving on southbound Foothill Road near Bernal Court.
Officers stopped the vehicle, a light blue four-door 1989 Chevrolet Caprice, and found an injured woman in a back seat of the vehicle. The driver of the vehicle, Andre Baker, had blood on him and was agitated, according to police.
While he was detained, officers determined that he and the woman were boyfriend and girlfriend, and that Baker appeared to have beaten the woman near the vehicle.
Baker was arrested on suspicion of domestic battery, assault with a deadly weapon, and violation of parole, and was booked into Santa Rita jail, police said.
The female victim was taken to Eden Medical Center to be treated for her injuries, which were not believed to be life-threatening, according to police.
Anyone who may have witnessed the incident is asked to call Pleasanton police at 931-5100.
