Strathclyde Police is urging communities to help officers tackle anti-social behaviour by warning people against buying alcohol for people under the age of 18.
The aim of the campaign, which kicked off yesterday, is to fight youth disorder, alcohol consumption on the streets, graffiti and other low-level crime affecting people in Glasgow and the west of Scotland.
During the crackdown officers will step up their work in pubs and off-sales by visiting licensed premises to try to stop young people from attempting to buy alcohol and to offer advice, support and reassurance to staff.
Workers will be reminded not to sell alcohol to anyone who is already drunk and to be aware that some people are buying booze for underage drinkers.
Schools will also be targeted in the clampdown, with posters warning them against underage drinking.
Police hope the campaign, which is running for four weeks, will significantly reduce the amount of alcohol getting into the hands of young people.
It will feature radio adverts, posters in schools and street stencils, as well as advertising within licensed trade publications and mirror stickers inside bars and clubs.
Chief Superintendent Bob Hamilton said: "There's no doubt that alcohol is a common factor in these crimes and what we want to do is raise the awareness about the impact it can have."
