Children out late by themselves this Christmas will be ordered home by police in Powys.
The Dyfed-Powys force said it wanted to protect youngsters from potential night-time problems during the busy festive period in Newtown.
Officers will target young people aged between 11 and 17, and could also take them to a safe place or phone parents to ask them to collect their children.
The scheme has been welcomed by Newtown mayor Joy Jones.
It is the idea of Insp Paul Ridley, who devised it when he worked for a police force in England and continued using it when he moved to Wales.
Insp Ridley said: "This strategy is part of our commitment to ensure that all members of the community receive an appropriate duty of care.
"With the Christmas party season upon us our towns will be getting busier with revellers, which can sometimes lead to anti-social behaviour.
"Therefore, we will be targeting children aged between 11-17 years old, who are congregating in town centres and ensuring their safety - make sure we don't pick up your child."
Newtown mayor Mrs Jones said it was a good idea.
She added: "It stops children from getting into bother and it will protect them at a busy time of the year."
