Police hunting the killer of a Chinese family in Northampton want to speak to Anxiang Du, who they say was a business associate of the murdered university lecturer.
Detectives investigating the murders of a popular university lecture and his family have released the name of a suspect.
Anxiang Du, 52, was described as a business associate of Jifeng Ding, who was found dead along his wife Helen Chui and their daughters Xing and Alice inside their detached house in Simpson Manor, near Wootton, Northampton, on Sunday. All four had suffered stab wounds.
Police said Du, who like the Dings was of Chinese origin, managed a Chinese herbal medicine shop in Birmingham and had “common business interests” with the family.
Det Supt Glyn Timmins said the possibility that Mr Ding had fallen out with Du over a business matter was “a line of inquiry that we are pursuing”.
Police said Anxiang Du was from the West Midlands and had ‘commong business interests’ with the dead man.
He added that he “did not believe” the killings were gang-related, despite newspaper reports speculating about the involvement of Chinese triad gangs.
Police are hoping to trace a five-door silver Vauxhall Corsa, registration BG60 PMO, which had been hired by one of the murdered family but disappeared from outside their home. It was last seen outside the house on Friday.
Det Supt Timmins described Du as a slim man who habitually wears a baseball cap to cover a bald spot, and is known to carry a rucksack.
He warned members of the public not to approach Du, who is thought to be scared and nervous, or the car and to call 999 instead.
Police revealed they have not yet found a murder weapon and are retracing Du’s last known movements. The suspect is thought to have got to Northampton on the train, then escaped in the missing car
Du left for work in Birmingham 1030am on Friday. He failed to return home, and left a suicide note behind, police said.
