More than 50 youths were dealt with during the five-week campaign and the number of anti-social behaviour calls to local police were cut by 20 per cent.

Operation Dampen launched in late July and between then and Monday this week saw officers and PCSOs from the Morley neighbourhood police team seize more than 120 bottles and cans of alcohol from underage drinkers on the town's parks and streets.

More than 50 local youths caught drinking or committing anti-social behaviour were dealt with during the operation, which officially concluded yesterday (Tuesday).

Action taken against the youths included taking them home and speaking to them in front of their parents and writing letters to parents advising them of their child's behaviour.

The operation also clamped down on those who were buying the alcohol, with fixed penalty notices issued to people for either buying or attempting to buy alcohol for a person under 18.

Insp Joanne O'Hare of the Morley NPT, said that not only had the operation been a real success but it had shown how seriously Morley police were taking the community's concerns about underage drinking and anti-social behaviour.

"The fact that the number of calls we've received about such problems has dropped so significantly during the operation shows that we're reacting to residents' concerns quickly and are not receiving repeated complaints about problem areas," she said.

Although the school term has started again this week, the NPT is keen to keep anti-social behaviour and underage drinking problems down.

"The clampdown may have officially stopped now school has started again, but that doesn't mean our efforts will stop," Insp O'Hare said.

"We will continue working to cut anti-social behaviour and underage drinking in our communities, and hopefully reduce the number of calls about these problems even more over the months to come."
