A professional actor will play the role of the robber in the simulated raids.

Nottinghamshire Police said an increase in armed robberies on post offices, banks and building societies had caused concern among local businesses about how to react during a raid.

The free classes will start later this month.

Mock raid

A police spokesperson said they hoped the mock raids would show employees how best to deal with dangerous situations without getting hurt.

Helen Mincher, crime reduction manager, who is organising the courses, said: "We are responding to the increasing concern of the local business community about robbery.

"Staff from Nottingham firms are being offered the unique opportunity to take part in a controlled, simulated robbery with a professional actor playing the role of an armed robber, which will be a powerful learning experience."

The police courses will be offered at Hucknall police station and will cover what to do during a robbery, measures to reduce the risk of robbery and coping strategies to lessen the effects of post-event trauma.

There are 40 free places being offered to businesses in Nottingham for the Armed Hold Up Safety Training Courses.
