Officers investigating the murder of the Ding family in Northampton last year have revealed they believe the prime suspect Anxiang Du is in Morocco.

The 53-year-old fugitive is suspected of murdering Jifeng Ding, his wife Ge Chui and their two daughters Xing, 18 and Alice 12 in their home on Friday 29 April 2011.

Police now believe he travelled out to Morocco shortly after committing the murders.

On Wednesday (4 July) officers travelled out to Madrid, Spain, to brief the Spanish authorities.

Detective Chief Inspector Tom Davies, leading the investigation, said: “We know that at an early stage in the investigation – in the first few days before he was declared the prime suspect, Anxiang Du had the opportunity to leave the country.

“We now strongly believe Anxiang Du left the UK soon after the murders and travelled from Victoria bus station, London on a coach to Paris, Gallieni. After this he travelled through France into Spain – most likely through the use of public transport. His final journey was to Algeciras in Spain where he caught a ferry from there into Tangier, Morocco.

“We believe that having made his way to Morocco, Mr Du is still there and may still be in the Tangier area. We have been working with the Serious and Organised Crime Agency, Interpol and Crown Prosecution Service International to ensure we have the support of international law enforcement agencies who are currently focused on locating Anxiang Du in Morocco.

“We are also closely working with the Moroccan police who have the required extradition papers should Mr Du be located and arrested in Morocco. This will ensure a swift process of bringing Mr Du back to England to face appropriate charges.

“We do not know yet why he chose this route but it appears he had this as a specific destination, using public transport and certainly avoiding major airports.“We are currently working with a number of agencies including Spanish Authorities to ensure that Mr Du does not use any other routes to travel into Spain, where we know he has previously travelled to on holiday.

"We are also urging those who are using or will be using the ferries from Algeciras, Spain to Tangier, Morocco to be aware of our manhunt.

“This visit to Madrid will allow us to spread the message wide and clear that we believe Mr Du used a specific route, will most likely be in Morocco and we are on the trail to find him. We want the communities in those countries to be on alert and call the police if they have any information.”
