Police are treating a huge straw blaze that broke out in a Suffolk airfield as a suspected arson.

The fire is believed to have been started between 4pm and 5.30pm on Saturday at the former Great Waldingfield airfield, near Sudbury.

Police said about 750 tonnes of straw were set alight, causing thousands of pounds worth of damage.

A group of boys and girls were seen on the straw stacks prior to the fire, which officers believe was started deliberately.
