Fire crews spent the night extinguishing a fire that has destroyed approximately 600 tons of crops, causing £40,000 worth of damage.
A spokesperson for Suffolk Fire and Rescue Service has said it is believed the fire, in Undley Road, was started deliberately.
The alarm was raised at 3.39pm, yesterday, and six fire engines and a water carrier remained at the scene overnight to ensure the fire was not spread to neighbouring fields of crops by strong winds.
Owner Brian Rutterford said he recieved a phone call at about 3,30pm from someone who had seen the bails of miscanthus alight.
Miscanthus is a crop used by power stations and for horse bedding, it had been bailed and was being stored in a field ready for collection to fulfil a power station contract.
Mr Rutterford said that if the wind had been blowing the other way the damage would had been much more severe.
