SAN JOSE, Calif. Four people were hurt Sunday when a driver crashed his car into a Wal-Mart and then assaulted customers inside, officials said.
The man hit two cars in the parking lot at about 11:15 a.m. with his red Oldsmobile Cutlass sedan, then crashed through the storefront near the pharmacy and collided with a beer display before stopping, police and witnesses said.
The unidentified driver then got out of his car and used a blunt object to attack people, San Jose police Officer Albert Morales said. The driver was arrested when officers arrived.
Investigators have not determined how fast the driver, described as a man in his 30s, was going at the time of the crash, but the car went about 20 feet into the Wal-Mart Supercenter, which had about 70 people inside in San Jose, Morales said.
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. The injured included a store employee.
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.
A Wal-Mart spokeswoman told the Mercury News that the store remained shut down for several hours, and an employee was among those hurt.
"We're obviously very concerned about the associate who was injured," spokeswoman Kory Lundberg said.
Shopper and witness Tianna Doan told the newspaper the employee was a cashier who was hit with the object and had a head injury.
Calls to the store by The Associated Press went unanswered Sunday.
