Thieves Steal 1,500 Litres Diesal
Police issue appeal after diesel is stolen from a compound near Winchester.
Police are appealing for information following the theft of 1,500 litres of diesel.
Between 11pm on Sunday 9 and 5.30am on Monday October 10, a large compound at Coxford Farm, Micheldever was broken into.
It's estimated that around 1, 500 litres of diesel was siphoned from six lorries on the site.
It's thought a vehicle stopped on the slip road of the A303 (Micheldever Station junction), a wire fence cut and the thief or thieves walked in and out of the compound with the fuel in containers.
PC Daniel Hunt who is investigating said:
"We think the smallest vehicle that could have been used to steal the fuel is a transit van and the offender/s must have spent a considerable amount of time committing the theft.
"Did you see a vehicle abandoned on the Micheldever station slip road east bound on the A303 between 11pm on Sunday and 5.30 on Monday?
"We'd like to hear from anyone who saw anything suspicious in the area."
Anyone with information is asked to contact Winchester police on 101 or call the Crimestoppers charity anonymously on 0800 555 111. Mini-Com users can call 01962 875000. From outside Hampshire and the Isle of Wight call 0845 045 45 45.
