A Lithuanian builder who sparked a manhunt after a couple were found stabbed to death in their home is being questioned by police on suspicion of murder.
Officers tracked down Viktoras Bruzas, 38, at around 6pm last night driving through Oxshott in Surrey - just five miles from the murder scene in the village of Fetcham, Surrey Police said.
A search for Bruzas was launched shortly after midnight yesterday when the bodies of Patrick and Gillian Kettyle, who were in their 50s, were found by a member of the family, believed to be one of their teenage children.
Detective Superintendent Nick May, from the Surrey and Sussex Major Crime Team, said the couple were killed in a "significant, violent and sustained" attack.
Mr May confirmed that Bruzas, also from Walton-on-Thames, was known to the couple though officers have refused to comment on speculation that he was in a relationship with a secretary at Mr Kettyle's building firm.
Detective Chief Inspector Mark Preston, from the Surrey and Sussex Major Crime Team, said: "This is a tragic incident which has shaken the close community in Fetcham.
"I would like to take this opportunity to thank everyone who assisted with the search of Viktoras Bruzas including members of the public and the media."
He added that he hopes the arrest will "goes some way to reassure the public that we have been relentless in our efforts during this fast-moving and on-going investigation".
Prior to Bruzas' arrest, police had been liaising with both the National Crime Agency and Interpol who were in touch with the Lithuanian authorities.
Another man in his 30s who was arrested at a property in Walton-on-Thames in Surrey yesterday has been released on police bail while the investigation continues.
Officers were called to The Copse, a quiet street of detached houses in Fetcham, at around 12.30am yesterday.
Police and masked forensics officers spent the day scouring the Kettyles' two-storey home in the quiet village near Leatherhead.
Much of The Copse was cordoned off with police tape, with yellow police evidence markers at various points up and down the street.
A section of nearby Meadow Way, which leads into The Copse, was also cordoned off after a knife was discovered beneath a large tree at the side of the road.
Officers also carried out a fingertip search of Meadow Way, checking gardens, and hedges, emptying household bins and even probing building work in a front garden.
Shocked residents said they often saw Mr Kettyle to say hello to when he was out walking his dogs, and described the family as being close and as "very nice, very friendly" people who kept themselves to themselves.
A local resident said she thought the couple lived at the house with a teenage son around 16 years old, and that she believed Mr Kettyle had other children from a previous marriage.
She said: "I think he inherited a building company from his father and works from home a lot."
Another elderly neighbour said: "It is just a very sad event, anywhere, but it is a quiet neighbourhood. A lot of the people have been here a very long time."
Formal identification of the couple will take place in due course.
