He was arrested on suspicion of the murder of his wife Lamduan Armitage, 36, whose partially-clothed body was found in a stream in the Yorkshire Dales in 2004.
Cops want to speak to people who knew them between March, 2004, up to September of that year when her body was found, when they lived in the village of Sprotborough, near Doncaster, South Yorkshire, and Preston, Lancashire.
Dad-of-two Armitage, who moved to Thailand with their children shortly after his wife went missing, was detained by Thai immigration police last month.
After he was bailed North Yorkshire Police made a further appeal for help from the public – specifically from anyone who may have known the couple while they were living in two locations in the months before she died.
The Sun tracked down dad-of-two Armitage to his remote home near Kanchanaburi where he worked as a lecturer.
