Three held over family murders
Police investigating the murders of a family of four in their own home have arrested three people.
University lecturer Jifeng Ding, his wife Helen Chui, and their two daughters Alice, 12, and Xing, 18, were found stabbed to death at their home in Wootton, Northampton, on May 1 last year.
Chinese businessman Anxiang Du, 52, who has not been seen since the day of the murders, is being sought by police.
He is a former business associate of Mr and Mrs Ding but their relationship had soured and was the subject of a court case which reached a climax in the week of the family's deaths.
A man and two women were arrested on Wednesday morning on suspicion of conspiracy to assist an offender, Northamptonshire Police said.
Police said a 54-year-old woman was arrested in Coventry, a 39-year-old woman in Gloucestershire and a 25-year-old man in London.
All three will be interviewed in police stations local to where they were arrested. The arrests were made as part of a joint operation involving the local forces and the East Midlands Special Operations Unit.
Three officers from the unit travelled to China - where family of the victims live - last month as part of the inquiry.
Detective Chief Inspector Tom Davies, who is leading the inquiry, said it was known that Mr Du also had contacts in China.
Anyone with information concerning the whereabouts of Mr Du is asked to contact police or Crimestoppers on 0800 555111, or via the website, www.crimestoppers-uk.org.
