EVENDALE, Ohio (AP) -- Police in suburban Cincinnati say it appears that someone is making a criminal career of robbing fast-food restaurants.
There have been at least 20 similar robberies in a little over three years, and each time restaurant employees have been forced into a walk-in freezer.
Fifteen robberies have been at an Arby's restaurant, and the description of the robber is often the same -- a white man wearing a mask and carrying a black handgun.
"All indications are that it's a high probability that it's the same individual," police Chief Gary Foust said.
He said his department is increasing patrols around fast-food restaurants, and officers will escort employees to their cars upon request.
Officers responded to the latest holdup Wednesday night when an employee used a cell phone to call police after being forced into a walk-in freezer with two other employees.
An employee leaving work was confronted by a man with a gun who took the woman to the employee entrance door, which was opened by another employee, police said.
Once inside, he ordered the employees into the freezer and told them to stay there, police said.
