Sledgehammer used in Rugeley Nationwide armed raid
Two armed robbers used a sledgehammer and a crowbar to break into a building society in a Staffordshire town centre.
Police said the robbery happened at about 19:25 GMT on Monday at the Rugeley branch of the Nationwide as security guards were delivering cash.
The robbers smashed the front door and demanded cash from the guards, while a third stood outside.
Officers said the men escaped with a "quantity of cash". No-one was injured in the incident.
They said all three robbers wore black balaclavas, clothes and footwear. It is thought they escaped in a silver estate car.
Staffordshire Police urged anyone with information to contact them.
