Ding murders: Police appeal to Anxiang Du
Police have made a direct appeal to the man suspected of stabbing to death a family of four at their home in Northamptonshire two months ago.
The bodies of Jifeng Ding, his wife Helen and their two daughters, Alice, 12, and Xing, 18, were found at their home in Wootton on 1 May.
Anxiang Du, of Coventry, was last seen on CCTV in London on 30 April, the day after the family were killed.
The detective leading the investigation has asked for Mr Du to give himself up.
Det Supt Glyn Timmins, Northamptonshire Police, said: "Anxiang Du, you are the only person that can tell me what went on in Wootton village on the afternoon of 29 April.
"I need to speak to you, I must speak to you, hand yourself in."
He added: "Take yourself to a police station, take yourself to a solicitor's office, anywhere you feel safe, but please contact me."
Mr Du, who worked at a herbal medicine shop in Birmingham, went missing a day after losing what has been described as a bitter court battle over his shared business interests with the Ding family.
Police believe he is still in the country.
A reward of £10,000 by the charity Crimestoppers has been offered.
