A documentary team have handed new information to lead investigators.

Madeleine McCann investigators have reportedly been given some "shocking" new evidence that could "heavily incriminate" the 15-year-old case's leading suspect. Individuals working as part of a documentary team behind an upcoming prime-time piece for German TV channel SAT.1 are said to have handed “many new clues and indications” to the detectives probing convicted paedophile, Christian Brueckner. Brueckner is already the subject of another documentary coming to Channel 5 which had initially been rumoured to supply evidence that would rule him out as a suspect. Brueckner is believed to have been staying in a camper van near the Ocean Club resort in Praia da Luz - a municipality in the Algarve region of Portugal - when the then 3-year-old went missing on May 3, 2007. He still remains the primary suspect at this time and police officers were even sent undercover to try and extract information from him in Oldenburg prison, Germany. Announcing the SAT.1 investigative: project entitled, 'New leads in the Maddie case. Is the German Christian B. the perpetrator?', journalist Jutta Rabe and her colleagues are said to have found material in Germany, England and Portugal, that points towards Brueckner being involved. While the documentary itself has no release date yet, SAT.1 Editor-in-Chief, Juliane Eßling says "the sad story of Madeleine McCann is a story that has many German facets" and that "there are many around him... who can describe individual details about the crime." Brueckner is now believed to be in solitary confinement but his alleged part in the long-running case will be heard in the Higher Regional Court of Braunschweig.
