A Chinese businessman wanted over the murder of a family of four in Northamptonshire has been extradited to the UK.
Anxiang Du was arrested in Morocco last year on suspicion of killing university lecturer Jifeng "Jeff" Ding, his wife Ge "Helen" Chui and their two daughters Alice, 12, and Xing, 18.
Northamptonshire Police said Du's extradition has been approved by the Moroccan Ministry of Justice in conjunction with the Home Office, and has arrived on a flight from Casablanca.

He will appear at Northampton Magistrates' Court on Thursday.
The family were found stabbed to death at their home in Wootton, Northamptonshire, on April 29 2011 - the day of the royal wedding.
Du, the prime suspect in the investigation surrounding the killings, was arrested by Moroccan authorities last July.
Detectives said at the time that they believed Du could have been evading capture in Morocco for more than a year.
He boarded a bus at London's Victoria station shortly after the family were found dead and travelled to Paris, through France and Spain, before catching a ferry from the port of Algeciras to Tangier.
The journey is believed to have taken only a few days, and Du had evaded capture in Morocco ever since.
Du has a background in herbal medicine and police said he had several thousand pounds in cash when he left the UK.
The suspect travelled from Africa in the custody of UK Border Agency officers, and will be held by the Metropolitan Police on arrival.
