An elderly man backed his Buick through the front of a Chinese restaurant, injuring two diners in Kingsport. Sergeant Joe Earles said police believe the driver was either trying to park or to leave a handicapped parking space by the restaurant’s entrance yesterday when he hit the accelerator. The vehicle came to rest with its rear two doors, back tires, trunk and bumper inside China Star next to super Wal-Mart on West Stone Drive. Two restaurant patrons were taken to the hospital. Their condition was not immediately available. Earles could not say if the driver would be charged.
