(CNN) - A man plowed a car through the front doors of a Walmart store in California Sunday, then attacked customers with a blunt object, police said.
The suspect drove more than 10 feet into a store in San Jose, California, got out of the car and began assaulting people, San Jose Police Officer Albert Morales said.
The suspect was arrested on assault charges and remained in police custody Sunday afternoon, Morales said. His motive was unclear, Morales said, but police believe drugs or alcohol may have been involved.
