A shopkeeper has been beaten with police style batons after they tried to detain a robber.

Remember folks, you are not allowed to keep a truncheon behind your counter to help you effect the lawful arrest of robbers, but of course robbers ignore the law and therefore are careful to make sure they can beat you senseless should try and lawfully detain them.

And if any of them get caught the person who sold them the batons will probably get a bigger fine than the robbers.
