Police trying to build a case against Madeleine McCann, main suspect Christian Brueckner, are said to be searching another property in Germany.
Officers would be present today with sniffer dogs in the city of Laatzen, near Hanover.
However, it is not yet clear what they are looking for on the site.
But the search, he says, is related to the case of the missing British toddler the sun.
During a house search in July in Seelze, 12 miles from Laatzen, the German police allegedly found a secret cellar.
The cellar is said to have been used by the German pedophile Brueckner, 43.
Locals claimed that years ago he lived on the site – a small hut on a concrete base – “off-grid”.
It is believed to have left in 2007 or 2008, with the structure demolished afterwards.
The latest search comes after the suspect in the photo was on his way to a hospital after allegedly attacked in court.
He had been to a court in Braunschweig, Germany, seeking parole on drug charges.
But the sex offender was reportedly attacked while waiting in a court cell and left with two broken ribs.
The hearing would be his first public appearance since he was named a suspect in Madeleine’s disappearance.
He is still serving a 21-month prison sentence for drug offenses and is eligible for release on January 6, after serving two-thirds of it.
Madeleine disappeared when she was three while on a family holiday in May 2007 at a resort in Praia da Luz, Algarve, Portugal.
The Daily Star has contacted the Braunschweig Public Prosecutor’s Office, which is leading the investigation into Madeleine McCann’s disappearance.
