Police are appealing for information after a field fire at Eye Airfield yesterday.
Emergency services were called to the field just minutes after midnight, where a 20 metre by five metre area of stubble and straw had been set alight.
The fire was dealt with within the hour.
A police spokesperson said it was the second call to the site in as many days.
Anyone who has information or may have witnessed the incident is asked to contact the Mid Suffolk North Safer Neighbourhood Team on 101.
