Wireless mobile phone technology is to be used to prevent trouble at a new skate park in Somerset.
The Midsomer Norton facility, which also includes an adventure playground, was opened last month.
Youngsters using the skate park, who have bluetooth switched on their phones, will receive text messages from the police reminding them to behave.
Sgt Pat Moore said it was an effective tool in the force's bid to cut down antisocial behaviour.
"It's been used effectively in Bath when pubs turn out. It's just to remind people to keep the area calm and behave properly," he said.
