A fugitive wanted by police over the murder of a man and the suspected murder of his missing wife was arrested in Luxembourg last night.
Fork-lift truck driver Ali Qazimaj, 42, had been on the run since Peter Stuart, 75, was found stabbed to death near his home at Weybread, Suffolk, on June 3.
His wife Sylvia, 69, has not been since and officers wanted to speak to Qazimaj about her whereabouts.
However, police now believe Mrs Stuart is also dead.
A 61-year-old man from Leicestershire was arrested as part of the investigation. He has been released on bail.
Detective Chief Superintendent Simon Parkes, of Suffolk Police, said today that officers had no expectation of finding Sylvia alive and were treating her disappearance as murder.
Qazimaj was eventually located and detained in Luxembourg yesterday on suspicion of the murder of Mr and Mrs Stuart.
A member of staff working at a hostel in Luxembourg identified Ali Qazimaj through photographs of him on the internet and then alerted authorities who detained him.
Detectives from Suffolk are now working with the National Crime Agency, the Crown Prosecution Service and authorities in Luxembourg to seek Ali Qazimaj's extradition under a European Arrest Warrant.
Police released CCTV footage of the last time the Stuarts were seen alive.
A senior police source in Albania said today: "We thank you for your cooperation. This will be invaluable to our investigation.
"We will work as hard as we can to help the British police. This could be the information that cracks the case.
"We strongly believe this man is not Kosovan but Albanian and he has connections with Albania."
Yesterday, British police revealed that Ali Qazimaj had remained in the country for at least three days following the killing.
He travelled to France the day after police said they had found Mr Stuart's body. Police believe Mr Stuart had been dead for a number of days.
Qazimaj, from Tilbury, Essex, abandoned his Citroen C3 in Dover, on June 4.
Qazimaj, who also used the name Marco Costa, then boarded a ferry on foot at 7pm the same day and travelled to Calais.
Police believe Qazimaj is from Kosovo.
He sought asylum after the conflict in the country ended in the late 1990s. This was granted and he was given a British passport.
However, since the hunt for him began, it has been suggested he may have stolen the identity of another Ali Qazimaj in Kosovo.
Detectives have so far declined to comment on these reports, or whether there were any traces of Mrs Stuart in Qazimaj's Citroen.
The last sighting of Mr and Mrs Stuart was at Goodies Farm Shop in Pulham Market, Norfolk, on the morning of Sunday, May 29.
Anyone with information which could help police should contact Suffolk police on 01473 782000.
