Police are looking for a suspect who held up a restaurant over the weekend.
According to police reports, officers responded to the Koto House, 70 Stockton Road, for a report of an armed robbery at 1:30 a.m. Saturday.
The owner told police that he was in the office after closing when a man wearing a ski mask and holding a knife approached him. The suspect demanded cash from the owner.
The owner told the suspect he had to go to the cash register; then told him it was already empty. The suspect then put down the knife, which he had obtained from inside the restaurant, and ran out a side door of the business.
Police described the suspect as 5 feet, 6 inches to 5 feet, 8 inches tall, with an average build. The mask he wore covered his entire face.
Investigators believe there was a second individual inside the business at the time of the attempted robbery, but the owner did not see him or her.
The suspect or suspects got into the restaurant through an unlocked side door.
Investigators ask anyone with information on the case to call the Sonora Police Department at (209) 523-8141.
