German police have completed their search of an allotment in connection with the disappearance of British girl Madeleine McCann, but did not say what, if anything, they had found.
Officers used sniffer dogs and an excavator as they dug up the site in the city of Hanover, with several police vehicles parked around a cordoned-off area.
The sky above the plot was declared a no-fly zone, according to a local newspaper.
Police revealed in June that they were investigating a 43-year-old German man in connection with the case, saying they believe he had killed the young girl. The suspect reportedly lived in Hanover from 2007.
Police began digging at the plot in the early hours of Tuesday.
They have given no details of how the search is connected to the case or what they hoped to find.
When contacted by AFP, Brunswick prosecutors and police declined to comment on reports that a cellar had been found.
Germany's Bild newspaper had reported that police had unearthed the foundations of an old building, along with a cellar.
Madeleine went missing from her family's holiday apartment in the Portuguese holiday resort of Praia da Luz on 3 May, 2007, a few days before her fourth birthday, as her parents dined with friends at a nearby tapas bar.
Despite a huge international manhunt, no trace of her has been found, nor has anyone been charged over her disappearance.
German prosecutors said in June they had "concrete evidence" that Madeleine was dead, despite British police continuing to treat her disappearance as a missing person case.
