A businessman suspected of murdering a family of four travelled to the victims' home just a day after losing a bitter court battle over their shared business interests, it has emerged.
Northamptonshire Police said Anxiang Du, who has still not been traced, is known to have caught a train from Birmingham to Northampton last Friday, when the family are thought to have been stabbed to death.
Mr Du, 52, was named as a suspect by detectives investigating the murders of university lecturer Jifeng Ding, his wife Helen and their two daughters.
Releasing CCTV images showing Mr Du at both Birmingham New Street and Northampton railway stations, Detective Superintendent Glyn Timmins confirmed that the businessman felt he was owed tens of thousands of pounds by Mrs Ding.
Addressing a press conference, Mr Timmins said officers had also established that Mr Du caught a bus from Northampton to Wootton, where the Ding family lived.
