Detectives investigating the murder of a Warwickshire farmer run over as he tried to stop his Land Rover from being stolen are seeking information about a P registered silver Mondeo.
Michael Boffey was knocked down in Withybrook, near Rugby, at about 11.20am last Saturday. Mr Boffey, known as Mick, died from head injuries at the scene of the collision at Grange Farm in Featherbed Lane.
The victim's Land Rover was later found about three miles away in a church car park in School Lane in the neighbouring village of Wolvey.
Officers believe the vehicle may have been abandoned on the site at about 11.30am. Forensic teams are studying the vehicle for clues.
A silver car is reported to have been seen with the Land Rover, both in Withybrook and in Wolvey.
Police are now keen to hear from anyone who may have seen anything suspicious involving a silver car last weekend, possibly a P registered Ford Mondeo.
They are also appealing to people in parts of Leicestershire, south Staffordshire and north Warwickshire who may have seen anyone in a vehicle matching this description acting suspiciously between 12.30am on August 20 and 5.30pm on August 21.
Anyone with CCTV footage or recorded images is urged not delete it and to contact the police.
Detective Inspector Andy Nolan, who is co-ordinating the murder enquiry, said: "We would like to thank all the members of the public who have so far come forward to assist us with information. The response has been very good and has provided us with valuable information."
Anyone with any information about the murder enquiry is asked to contact the incident room on 01926 415795.
