Detectives investigating the brutal murder of the 76-year-old retired farmer at his Chittering home have said forensic examinations of the converted farmhouse will continue until the end of January. Two people, a 22-year-old man and a 21-year-old woman remain on police bail in connection with the investigation, but otherwise police are still following leads from December. The body of Mr Thomas was discovered by police at his home in Ely Road shortly after 12.30pm on Sunday, December 18. Police believe the murder may have been the result of a botched robbery. He was last seen alive at about 6.30pm the previous evening. His silver Rover 75 estate was discovered in Church Lane, Milton at about 11pm on the Saturday night before his body was found. Detective Superintendent Jeff Hill said: We have been carrying out forensic examinations at the house since the discovery of Mr Thomas body. A number of submissions have been made for analysis, but there is still a lot of work to be done. We believe at least two people were in the house when he died, if there is a trace of them in the property we will find it. Mr Thomas, a widower who had an interest in classic cars, moved to Cambridgeshire from Wales 12 years ago. He leaves behind a son who lives in London. Police are continuing to appeal to witnesses who saw Mr Thomas silver Rover between Chittering and Milton. It had mechanical problems and would have made a lot of noise when being driven and could only manage low speeds.
