"Sky News is not revealing the suspect's identity for legal reasons and Scotland Yard has not named him.The suspect's name was given to the Metropolitan Police in 2017 after the 10th anniversary of Madeleine's disappearance.
A former neighbour of the suspect said: "He arrived in the mid-90s and rented the place from the English owner.
"He went back to Germany at one stage and moved another German guy in to look after it, then came back and threw him out on the street.
"He was always a bit angry, driving fast up and down the lane, and then one day, around 2006, he just disappeared without a word. I think he left some rent unpaid."
The neighbour added: "About six months later I was asked to help clean up the place and it was disgusting, absolutely vile. It had been trashed, with broken stuff like computers all over the place.
"We found a bin bag and inside were wigs and exotic clothing, whether just fancy dress or something stranger I couldn't tell." "
