Anne Darwin, the wife of back-from-the-dead canoeist John Darwin, has arrived back in Britain and been arrested, according to the Daily Mirror’s website.
Mrs Darwin is expected to be questioned by detectives later today, it added.
It did not say which airport she had flown into.
Cleveland Police last night charged Mr Darwin with making an untrue statement to procure a passport and obtaining a money transfer by deception in relation to a life insurance policy.
Mr Darwin will appear in court tomorrow.
He will remain in police custody today and Detective Sergeant Iain Henderson, of Cleveland Police, said an application would be made at Hartlepool Magistrates’ Court tomorrow to remand him in custody.
Det Sgt Henderson has been urging Mrs Darwin to contact police, saying that if she did not do so, police would be making inquiries to trace her.
He said Mr Darwin was “fit and well at the moment”.
He could not say if there would be more charges.
He also said he could not disclose whether the investigation would be extended to look at members of the Darwin family.
Mr Darwin was arrested on Tuesday at his son’s house in Basingstoke, Hampshire, on suspicion of fraud and was then taken to the North East for questioning.
He disappeared from his home in Seaton Carew, near Hartlepool, in March 2002 and was presumed drowned after his wrecked canoe was found.
But last Saturday he walked into a London police station, saying he had amnesia.
It today emerged that he had written a short message to his elderly father from his cell, the first contact between the pair since he went missing more than five and a half years ago.
Ronald Darwin said the note read: ’Dear Dad. Just to let you know, please don’t worry.’
“Every time the phone rings, I grab it thinking it might be John but it never is,” he told the Sunday Mirror.
Mrs Darwin has given several interviews to journalists since flying out of Panama which she made her home seven weeks ago.
The couple’s sons Anthony and Mark released a statement earlier this week, saying they wanted no more contact with their parents.
They asked: “How could our mam continue to let us believe our dad had died when he was very much alive?”
John Darwin’s aunt Margaret Burns, 80, said of the case today: “It’s beyond satire. You couldn’t make it up. It never occurred to me it would get this big.”
