The Inn Keeper system replaces a record book and will store information about incidents of poor behaviour.

It means police can quickly identify known trouble spots or pubs with a history of under-age or late drinking.

They will then be able to allocate officers accordingly and also be able to draw up and view the history of a pub when its licence is up for renewal.

'Quick search'

Officers say the new logging system has cut alcohol-related crime in nearby Nottingham by 18%.

Chief Insp Paul Elliot said: "It helps us to catalogue the licensed premises throughout the whole county and also to take note of any trouble that we have at those premises.

"It's basically a very quick search engine so that we can find details of when these things happen and then spot those areas and take specific action to deal with them.

"It will put an emphasis on licensees to be sure that people who they're serving drinks do not leave their premises in a drunken state and cause problems in the street."
