Anxiang Du, a business associate of the Family stabbed to Death in Northampton is wanted for Questioning by the Police for their Murders -3rd May 2011

Detectives investigating the murder of a family of four found stabbed to death in Northampton have named a man they want to speak to in connection with the killings.

The suspect, 52-year-old Anxiang Du, is a business associate of the deceased family and of Chinese origin.

He was last seen at his herbal medicine shop in the Pallasades Shopping Centre, Birmingham, on April 29 wearing a white baseball cap, brown waist length coat and a blue woolen top.

Mr Du left what appears to be a suicide note at the shop saying goodbye to his family.

Detective Superintendent Glyn Timmins said: "Mr Du routinely wears a baseball cap as he has a bald patch at the back.

"We believe that he may have with him a rucksack which he wears across him. We would seek the public assistance in finding Mr Du so that we can question him."
