James Gray, the horse trader who was found guilty of neglecting more than 100 animals on his farm, was photographed at a horse fair just weeks after a judge said he was to have no contact with equines.

Gray, 45, was sentenced last month along with four members of his family for the cruelty he inflicted at Spindle Farm, Amersham.

Pictures have now been handed to Thames Valley Police showing the trader at Langley Market, in Slough, Berkshire. In one photograph, Gray can be seen with his son, James Gray, 16, standing in front of three horses, talking to another man. In another picture, he and his son are seen standing in a horse box, watching as an animal is led up the ramp.

The pair were prevented from having any dealings with equines after vets uncovered a "horror" scene at the Buckinghamshire farm when they went to look round in January last year.

Inspectors found horses with little bedding and crammed into pens ankle-deep in their own faeces. Hooves and body parts were discovered scattered across the site, along with a mound made up of bones and skulls. Some of these had been burned and dumped on a bonfire, while others were simply left lying on the ground, covered in rubbish.

RSPCA inspector Kirsty Hampton, who visited the farm in the early stages of the investigation, described the suffering she witnessed as "distressing beyond measure" and said it was the worst case of animal cruelty she had ever seen.

District Judge Andrew Vickers handed Gray a six-month sentence and ordered him to pay £400,000 at Aylesbury Magistrates' Court, relating to a series of charges under the Animal Welfare Act 2006. He was also banned from having any dealings with equines for 10 years.

James junior was similarly banned from having any contact with the animals and placed under an 18-month supervision order. They launched an appeal against their convictions and Gray was released on bail, on the condition that he had no dealings with horses.

His wife, Julie, and children Cordelia, Jodie and James junior, were also appealing against lesser convictions under the Animal Welfare Act 2006. The photographs, taken last week, were handed to Thames Valley Police by The Sun newspaper. A police spokesman said: "Any intelligence Mr Gray has committed further offences will be fully investigated."
