Officers confiscated more than 50 bottles of alcohol during one night in a Derbyshire town.
Police seized the alcohol from underage drinkers on Circular Drive in Eckington earlier in June.
The offenders, who were aged 16 and 17, were asked to leave the area.
It was part of a campaign to tackle antisocial behaviour in the town following residents' complaints to police.
Police community support officer Dale Merchant said: "We take reports of antisocial behaviour and underage drinking seriously.
"Alongside the alcohol confiscations we have issued a number of nuisance letters.
"If the youngsters persist with this type of behaviour, we will put them on an acceptable behaviour contract (ABC) to help limit their behaviour."
