People across the area are being urged to be vigilant following an increase in the number of diesel thefts.
Police in Chichester are asking people to report any sightings of people acting suspiciously in response to three diesel thefts which took place between August 26 and August 31.
The first took place between 8pm on Friday, August 26 and 6am on Saturday, August 27 in Main Road, Bosham, when around 200 litres of diesel were stolen from a tractor.
The second took place between Friday, August 26 and Tuesday, August 30 in High Street, Bosham, when 40 to 60 litres of red diesel were stolen from a crane.
The third theft took place between 6.30pm on Tuesday, August 30 and midday on Wednesday, August 31 when diesel was syphoned from two combine harvesters.
