Detectives are investigating whether a man suspected of stabbing his three-year-old son to death is related to a wanted evangelist.

Officers are examining possible family ties between Paul Otieno, 31, and flamboyant millionaire pastor Gilbert Deya.

Kenyan prosecutors want to put Mr Deya on trial over claims he abducted "miracle babies" and handed them to infertile followers in Britain.

After being arrested several times by Scotland Yard officers, he continues to battle against extradition from his base in Peckham, south east London.

Otieno remains under arrest in hospital in a serious condition after attempting to kill himself. He has wounds to his throat and body.

Police believe he stabbed his three-year-son Wilson to death and attempted to murder his wife, Jacqueline, 28, when she threatened to divorce him.

When officers arrived at their flat on the Lynton Estate, in Bermondsey, south-east London, on Monday, they found his 17-month-old baby daughter unharmed. Mrs Otieno was taken to hospital suffering a slash wound to the neck and has since undergone further surgery.

Neighbours said the family were regular churchgoers but is not clear if they attended the Gilbert Deya Ministry in Ormside Street, Peckham. They had lived in the block of flats for about a year and Otieno was also known by the name Paul Deya.

Gilbert Deya, 57, who has claimed he was consecrated as an archbishop in the United States in 1992, faces five allegations of child kidnap between 1999 and 2004.

He is the head of the Gilbert Deya Ministries religious movement, which at one point boasted a private jet emblazoned with his signature.
