"Peter W bought a Volkswagen T3 Westfalia campervan from Christian Brueckner in 2015 - but police have now seized it and taken it back to Germany for forensic tests"
In 2015, Peter W, of Regensburg, southern Germany, paid suspect Christian Brueckner £5,000 for his yellow and white Volkswagen T3 Westfalia campervan in the Algarve, Portugal.
Police seized it from Peter W’s scrapyard and shipped it to Germany for forensic tests.
Experts are examining it for clues into three-year-old Madeleine’s disappearance from a holiday apartment in Praia da Luz in 2007.
