A 17-year-old boy has been arrested after seven specially-adapted minibuses, used by people with disabilities and schoolchildren, were destroyed in a fire.
Nobody was hurt in the blaze, but the minibuses, worth up to £250,000, were destroyed at Silk Mills Park and Ride compound in Bishops Hull, Taunton, Somerset.
Police said a teenager from Taunton had been arrested on suspicion of arson, assault by beating of an emergency worker, and affray following the blaze, which broke out at about 19:50 BST on Saturday.
Justin Popes, coordinator of the minibuses' routes, said: "As a parent with children with additional needs, it would kill me if their mood was upset by [this] change."
