About 30 firefighters were called to tackle a blaze on agricultural land at Easton tonight which involved 600 tonnes of bailed hay.

At its height five appliances, including crews from Carrow, Earlham, Wymondham and Dereham, were involved in trying to bring the fire, at Broom Lane, Easton under control.

The fire service was alerted to the fire, on agricultural land which forms part of the Easton College estate, at about 4.30pm.

About 15 firefighters remained on scene at about 10pm with crews expected to remain overnight and throughout the day tomorrow.

Watch Manager Richard McGonagle, incident commander, said they were not able to say what started the blaze but 'haven't ruled out anything, that includes deliberate ignition'.

There were three main seats of fire with one close to a shed which contained asbestos sheeting.

Other nearby hazards included a tank full of liquid nitrogen and power cables running through the site.

But Mr McGonagle said it was in an isolated spot and that no-one had to be evacuated.

He said the fire was under control but might take several days to burn out.
