A new appeal has been made for information about a raid on the home of a Derbyshire antiques expert.
On 17 March James Cartland, 64, was threatened and tied up by three men at his house in Church Street, Ashbourne.
Mr Cartland said at the time he believed the raid was linked to his appearance on a TV show because the gang targeted antiques.
Police have renewed an appeal for witnesses, reminding people a £5,000 reward has been offered.
While his house was being searched, Mr Cartland managed to raise the alarm, forcing the offenders to abandon the items collected.
Two of the gang were white and one was black but all wore face coverings.
A police spokesman said: "We believe the men must have used a van or other large vehicle as they planned to transport antiques from the house.
"Crimestoppers is offering a £5,000 reward for information leading to the arrest and conviction of the men."
