Moves to stop underage drinking spoiling autumn festivals have been announced by police in Leicester.
Officers will mount increased police patrols in selected areas of the city during half-term week, Halloween, Bonfire Night and Diwali.
Alcohol will also be confiscated from under-18s and suspect groups of young people will be dispersed.
Ch Insp Chris Haward said families should not have the season of celebrations spoiled by drunkenness.
He added: "We will be targeting the people who cause these problems, as well as licensees selling to children.
"We also intend to write to the parents or guardians of the children involved detailing their behaviour and offering guidance in relation to alcohol misuse."
There will also be another test-purchase operation, targeted at licensed premises in the city that are suspected of selling alcohol to underage customers.
This follows an operation in September where 14 out of 20 places in Leicester sold alcohol to an underage mystery shopper.
