The suspected killer of former EastEnders actress Sian Blake and her two sons has been arrested in Ghana.
Arthur Simpson-Kent, 48, was armed with a 'knife and a spoon' when he was detained in the coastal town of Takoradi, 150 miles from the Ghanian capital Accra.
He was tracked down by Ghanian detectives after leaving the UK for the west African country on December 19.
He has been wanted since the bodies of Ms Blake and their two sons Zachary, eight, and Amon, four, were found on Tuesday buried in shallow graves in his family's back garden.
Interpol's director in Ghana said: 'He has been arrested. He had a knife and a spoon on him.'
Four Met officers had also travelled to Ghana as part of the investigation.
The hairdresser and former model arrived in the capital city Accra on December 19 - three days after police questioned him at the family home in Erith, Kent.
Officers plan to drive him back to the capital city Accra as soon as possible.
A Scotland Yard spokesman said: 'Detectives have today, Saturday, 9 January, been made aware of an arrest in Ghana.
'We are currently working alongside the Ghanaian authorities but are not in a position to discuss further at this time.'
It is understood concerns about domestic violence were raised by a relative of Ms Blake to the NSPCC on December 16.
A missing person's investigation started on the same day after police attended the family home in Erith, Kent.
On Tuesday - almost three weeks later - three bodies were discovered in the garden of the property, triggering a murder inquiry.
ITV News obtained photographs of Simpson-Kent, 48, at Kotoka Airport in the Ghanaian capital Accra - three days after he was quizzed by police over the family's disappearance.
On Thursday Ms Blake's sister Ava said Simpson-Kent will have to 'answer to God', revealing that her sibling had told their mother, Pansy, that she wanted to get out of her relationship 'a long time ago'.
Ms Blake, 43, had motor neurone disease - a fatal, rapidly progressing illness which affects the brain and spinal cord - and was reportedly looking 'very frail' before she vanished.
An investigation by the Independent Police Complaints Commission (IPCC) into how police handled the case was officially launched on Friday.
Concerns about Miss Blake's welfare were passed to the Met Police before it officially launched a missing persons inquiry.
The IPCC said police began their inquiries following a 'report of concern' by visiting the home where officers spoke to Simpson-Kent.
The watchdog said: 'Sadly, the bodies of Sian and her two children were found at the Pembroke Road address 20 days later, on 5 January 2016.
'The Independent Police Complaints Commission (IPCC) investigation will examine the police response, actions and decision-making following the reported concern for welfare.'
