4 Hurt in Crash, Attack at California Wal-Mart Four people were hurt Sunday when a driver crashed his vehicle into a Wal-Mart and then assaulted customers inside, police said. Investigators have not determined how fast the driver - described as a male in his 30s - was going at the time of the crash but the car went about 10 to 20 feet into the store in San Jose. About 70 people were inside at the time, police Officer Albert Morales said. After the crash at around 11:15 a.m., the unidentified driver got out of his vehicle and used a blunt object to attack people, Morales said. The driver was arrested when officers arrived.

He did not know the extent of the injuries to the three other people but said they were not life-threatening. Customer Sharon Kaye told the San Jose Mercury News the driver sideswiped her car as he made several runs around the parking lot before driving between poles at the entrance and crashing into the store. "At first, I thought I may have done something to anger him while driving," she said. But then I realized he was out to get into the store. After the crash, the entrance to the Wal-Mart was roped off with yellow police tape, and workers put up large boards covering the automatic doors where the car had entered. Calls to the store by The Associated Press went unanswered Sunday.
