A TEENAGER wanted on suspicion of assault has climbed on top of a Rishton school to avoid arrest.

The 16-year-old was spotted near Rishton High School in Stourton Street and staff at the school called police.

The boy climbed on to the roof and a stand-off has developed with the boy refusing to come down.

Police cordoned off Stourton Street and a police helicopter monitored the scene from the sky.

A crowd of about 50 people had gathered at the scene.
