An adventure playground at a community farm has been hit by suspected arson. No one was inside the Bristol premises at the time, said the city farm, which added that the adventure playground building would be closed until further. City farm interim director Ariaf Hussain said: "This is a real setback for the farm. The adventure playground building is a significant community resource offering activities for toddler groups, youth clubs and adult learners." He added: "The farm is just recovering from a tough couple of years."
