Detectives investigating the murder of Bradford grandfather Clement ‘Butch’ Desmier (pictured) were last night continuing to question a teenage suspect.

The 19-year-old man was arrested in Bradford on Saturday in connection with the murder of 68-year-old Mr Desmier, who was found with multiple injuries in his ransacked home in August. He remained in custody last night.

The arrest came after new information and a fresh appeal from Mr Desmier’s daughter, Adelle Peterson, was broadcast on the BBC TV Crimewatch programme late last month.

Detectives from West Yorkshire Police’s Homicide and Major Enquiry Team, which is investigating the murder, were yesterday granted a further 36 hours by magistrates to continue questioning the teenager.

Mr Desmier was found dead at his home in Rowlestone Rise, Greengates, on Thursday, August 23. Police revealed he was found in his armchair with a pillow over his head. He was found with 70 separate injuries, including 40 stab wounds, and had been tortured before he was killed.

His body was found by a neighbour who had gone to check why Mr Desmier’s lights were on during a summer’s afternoon.

During Crimewatch, a reconstruction of Mr Desmier’s last-known movements took place, along with the emotional appeal. More than 20 calls were made to police, including two which were of “significant interest.”

Earlier, the man leading the murder investigation, Detective Superintendent Mark Ridley, appealed through the Telegraph & Argus for anyone with a guilty secret to come forward.

Police had spoken to more than 700 people since the murder and distributed 12,000 leaflets, appealing for information, around Greengates and Ravenscliffe.

There had also been a £5,000 reward on offer from Crimestoppers for information leading to the arrest and conviction of the killers.

Officers are still appealing for anyone with any information to contact the Homicide and Major Enquiry Team on 101.
