Campaigning pupils are calling on Bradford Council to tackle problems at a play area which has become a teenage drinking den.

Children at Crossflatts Village Primary School said broken glass was putting them in danger at the popular recreation ground - a recognised gathering point for drinkers.

As part of a classroom environmental project, the pupils wrote to Bradford Council asking for changes at the park.

Teacher Isobel Roberts said a weekend inspection had revealed an alarming amount of broken glass among the wood chippings beneath the swings, among other places.

"There are two metal benches there but the only bin is not nearby so consequently bottles are ending up on the ground," said Mrs Roberts.

"It is so dangerous because it is mixing amongst the woodchip. The children's play area needs a fence around it and more litter bins are needed by more vandal-proof benches away from there."

She also called for a cushioned black rubber surface to replace the chippings which would make broken glass easier to see.

The Morton Lane school decided to tackle the problem, with pupils writing heartfelt letters to Bradford Council.

Pupil Phoebe Dawson-Watts wrote: "We have been doing a project about making our school environment safe and clean. Unfortunately, when I go down to the recreational ground park it is in a dreadful state because there is lots of glass on the floor. Please can you help us?"

Mrs Roberts, who has campaigned on the issue with Crossflatts Village Society, said she was impressed by the pupils' direct approach.

"We have a school council so the children are used to voicing their opinions about important matters," she said.

"The pupils are interested in things not just in school but around it too. They enjoy extending their reach to help the whole village."

Sergeant Esther Hobbs, of Bingley police, said the recreation ground was among the areas officers were keeping an eye on.

"It is not somewhere where there is a huge problem but we have received reports of youths," she said. "We are monitoring the situation."
