Arsonists targeted a school in the early hours of this morning.
Five wheelie bins of paper and cardboard were gathered and set alight in the grounds of Sir Christopher Hatton School, Wellingborough, at about 3.50am.
Heat from the fire was so intense it radiated to a nearby shipping container, damaging roof tiles and other items stored there.
A fence panel was also destroyed in the fire as well as the bins and the waste waiting to be recycled in them.
Firefighters from Wellingborough Fire Station used hoses, a thermal imaging camera, lighting and rakes to tackle the fire.
The fire service said the fire was started deliberately.
