Sian Blake's boyfriend, Arthur Simpson-Kent, was taken into custody for allegedly murdering the former "EastEnders" star and her two children, according to The Guardian.
Simpson-Kent was picked up by authorities at London's Heathrow airport on his return to the U.K. after being extradited from Ghana.
The soap star and her two sons, Zachary, 8 and four-year-old Amon, went missing on Dec. 13 and were found dead, buried in the garden of Blake's home in Erith, Kent on Jan. 6 with head and neck injuries, according to BBC News.
Simpson-Kent, a hairdresser by profession, fled the country after Blake and her kids were reported missing. He was arrested on a beach in Ghana's coastal town of Butre five days after the bodies were discovered.
Blake played the role of soul singer Frankie Pierre in 56 episodes of the soap opera from 1996 to 1997 and had been suffering from motor neurone disease. Her other television credits include "The Bill," "Casualty," "Doctors" and "Skins," according to Daily Mail.
Scotland Yard is currently at the center of an investigation carried out by the The Independent Police Complaints Commission over it's handling of the case and why it took them until January to find the bodies.
