Norfolk Police are appealing for information after two arsons in the Long Stratton area last month.
The first incident took place at the junction of Manor Road and Flowerpot Lane in the village, sometime between 8.30pm and 9.15pm on Wednesday, March 30, when officers received reports a bin had been deliberately set on fire at a bus stop.
The second took place sometime between 4pm and 6pm on Thursday, March 31.
An unknown number of suspects set fire to a stack of straw bales located at a farm off Church Lane in Stratton St Michael.
The fire spread to a large chicken shed, which did not contain any livestock, which was completely destroyed.
Anyone with any information is asked to contact PC Grahame Bartlett at Norfolk Constabulary on 101 .
