Police have urged parents to speak to their kids after a group of teenagers set fire to play equipment in a park.

Officers were called to help the fire service after a group of 13 to 16-year-olds lit the fire in Carpenders Park off Oulton Way yesterday evening.

Three Rivers Police last night wrote on Facebook asking parents whether their children smelled of smoke when they got home.

They added: "The fire was started on a bit of the play equipment which was swiftly put out by our colleagues in the fire service.

"Not only is this behaviour incredibly dangerous and idiotic, it's time consuming for our emergency services and also damages valuable bits of equipment for local children/families.

"There is footage available but I would urge parents to have conversations with their children if they feel they have been involved."

Herts Fire Service tweeted: "20:15 Control Received a call to children lighting fires in the park at Oulton Way, Carpenders Park.

"@Watford_Whites were mobilised and put out the fire using a backpack sprayer.

"The police were called due to the nature of this incident."
