Police in Concord and Walnut Creek are searching for a man who they say is responsible for a rash of robberies over the past month.
The most recent robbery happened Wednesday night when police said the suspect calmly walked into a Baskin-Robbins and demanded cash. Police said the suspect, who was wearing sunglasses and a hooded sweatshirt, was in and out of the business in less than a minute.
"His [modus operandi] is he comes in so nonchalant and will enter when no customers are inside," Concord Police Cpl. Christopher Blakely said. "It's just him and the employees."
In another robbery, the suspect calmly walked int a Subway in Concord and demanded cash.
That is exactly what happened to Leslie Glaze, who said the suspect walked into Caspers Hot Dogs in Walnut Creek and flashed a knife.
"He said 'Open the drawer and give me the money and I won't hurt you'," Glaze said. "He's done it before. He was just way too calm."
In the last month, police believe the suspect has hit eight businesses throughout Walnut Creek and Concord. At one point, the suspect robbed a Subway and a NorCal Swim shop on the same day.
Police said the suspect three days later robbed three more businesses in a 24-hour span.
"On all those occasions there was a weapon, either a gun or a knife," Blakely said. "So he is considered armed and dangerous."
Concord police describe the suspect as a man standing about 5 feet 7 inches tall, with a thin build.
Glaze is hoping the suspect is caught soon.
"You never know what he might do if you don't give him the money," Glaze said.
