Vandals went on the rampage at a Rugby special school at the weekend and let all the animals out of the outdoor learning area.
Staff and children have been left “heartbroken” after a trail of destruction was left at Brooke School in Overslade Lane.
The culprits damaged the school’s minibuses, outdoor stores, forest school and farm log cabins.
Headteacher Chris Pollitt said: “We have no idea why anybody would want to do this.”
The damage also included the destruction of four willow grown chairs that had been grown and nurtured by the students over the last few months.
“In the farm the animals were released from their enclosures,” said Mr Pollitt.
“The school minibuses were vandalised with windows smashed, tyres slashed. Outdoor stores were broken into and chemicals used in the school pool were thrown across the floor.”
Specialised tools and cooking items were also taken.
Mr Pollitt said staff tried to hide a lot of the damage from the children.
He added: “There is an intense level of frustration that these actions could cause so much damage to our very special community.”
Three teenage boys were arrested on Saturday afternoon following reports of a burglary and suspicious activity at two schools in Rugby.
Warwickshire Police received reports of the burglary at Brooke School and of three males acting suspiciously at Harris School in Harris Drive between 3pm and 3.30pm.
The three teenagers, who are aged 15, 16 and 17, were arrested nearby and taken into custody for questioning. They were later released on police bail pending further enquiries. Anyone who has any information which would help the police with their enquiries should call 101 or Crimestoppers anonymously on 0800 555111.
