German police completed their search of an allotment in connection with the disappearance of British girl Madeleine McCann on Wednesday.
Police have been carrying out a search since Tuesday morning in a garden near Hanover.
McCann went missing on May 3, 2007, at the age of three, at a resort in Praia da Luz, on Portugal's Algarve coast.
The case recently came back into the news after German prosecutors said they believed McCann was dead in June.
They said that a murder probe was opened after a new suspect was identified in the case.
The suspect, who was not named by police but identified by German media as Christian B., reportedly lived in Hanover from 2007.
Police gave no details of how the allotment search is connected to the case or what they hope to find.
Germany's Bild newspaper reported that police had unearthed the foundations of an old building, along with a cellar, which an unnamed neighbour said was part of a building that had stood there long before the suspect B. took over the plot.
The UK's Metropolitan Police said in June that the suspect was a 43-year-old German man who is currently imprisoned in Germany.
According to Germany’s Federal Criminal Police Office, the man was jailed for a sexual crime.
He had lived on and off in the area in Portugal at the time of McCann's disappearance.
