4 hurt in crash, attack at California Wal-Mart AP 3/31/2013 10:49:23 PM (AP) 4 hurt in crash, attack at California Wal-MartSAN JOSE, Calif.Four people were hurt Sunday when a driver crashed his vehicle into a Wal-Mart in California and assaulted people in the store, police said.After the crash, the driver got out his vehicle and used a blunt object to attack people, said San Jose police Officer Albert Morales, a department spokesman.One person suffered what Morales described as serious injuries. He did not know the extent of the injuries to the three other people but said they were not life-threatening.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. About 70 people were inside at the time of the incident, Morales said.It's not known what prompted the attack, but Morales said the driver was "uncooperative." The driver of the vehicle, who was not identified, was arrested when officers arrived.One witness told the San Jose Mercury News the driver made several runs around the parking lot before driving between poles in front of the entrance and crashing into the store."At first, I thought I may have done something to anger him while driving," Sharon Kaye told the newspaper. "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. Police were interviewing witnesses and about 30 employees stood watch outside.Calls to the store by The Associated Press went unanswered Sunday.
