TEAMS of undercover underage "drinkers" have helped to slash illegal sales of booze to youngsters, a report claimed yesterday.

Now the policy looks likely to be extended in the hope it will have similar effects on sales of aerosol sprays and cigarettes.

Last year, trading standards officers in County Durham launched a new drive to increase the use of young volunteers visiting shops to make test purchases of age-restricted products such as alcohol, tobacco, aerosol spray paint and fireworks.

A report to Durham County Council's Cabinet next week from Acting Director of Environment David Miller shows that the number of shops breaking the law fell from 12 per cent of those tested down to just three per cent.

But, the report concedes, some of the fall may be explained by unscrupulous traders getting wise to the tactics employed by enforcement officers.

Mr Miller's report suggests: "There is anecdotal evidence to suggest traders are becoming wary of selling to children they do not know, but are still selling to local children.

"Our policy not to use young people who are local to their areas prevents us from testing this, but we are piloting alternative joint enforcement strategies with the police who are targeting street confiscation of alcohol from youths and those selling to them around known trouble spots and then tracing it back to the supplying retailer.

" Hopefully, this will prove an even greater deterrent to those retailers willing to sell alcohol to local children."

The report concludes that, while underage drinking has been targeted in response to public concern, children may find it easier to buy other age-restricted products.

Mr Miller will recommend that the authority steps up its efforts to achieve similar results in relation to tobacco and aerosol spray paints, where the percentage of illegal sales last year reached 33 per cent and 42 per cent of all attempted test purchases.

Mr Miller said: "There still seems to be a temptation to sell tobacco products to young people, and despite targeting shops in or near to graffiti hotspots throughout the County, we were dismayed to find illegal sales of aerosol spray paint were still being made to our volunteers, despite prior advisory mail shots and visits."

Cabinet members will be recommended to put a greater emphasis on targeting illegal tobacco and aerosol spray paint sales in addition to under-age alcohol.
