Madeleine McCann's police were looking for new property in Germany today, months after digging up a nearby parcel.
Police and sniffer dogs descended on the house near Hanover where the suspect Christian Brueckner once lived after receiving a tip from a member of the public.
Officials were on the scene early Wednesday morning, but the current residents of the house turned out to be "completely impeccable" citizens, and the eight-hour search ended with no apparent breakthrough.
Authorities did not provide official details of the search, but local newspaper Neue Presse said it was linked to the Madeleine case.

The assessment of today's search was so optimistic that a spokesman even suggested that the tipster could be investigated for a false complaint.
In July, German police searched a vegetable garden 12 miles away that was once occupied by Brueckner and excavated the parcel in a two-day operation.
The parcel was a short drive from an apartment block where Brueckner was registered during his stay in Hanover, and the & # 39; Havana Club & # 39; bar, which he believed to have been to, is also nearby.
A gardener said in July that Brueckner lived off-grid when he was allocated in 2007 and talked about planning his return to southern Europe.
I remembered his face from the pictures on the news. And I remember his van and his dogs. I had completely forgotten him by then, "said Wolfgang Kossack, 73.
According to German media, Brückner has received at least two criminal convictions from a Hanoverian court, one for falsifying documents in 2010 and one for theft in 2013.
Prosecutors in Hanover said that he had split his time between 2013 and 2015 between Germany and Portugal.
Brueckner lived in the Algarve for much of the time from 1995 to 2007, and German prosecutors said he had received a call from a Portuguese number at the time of Madeleine's disappearance in May 2007.
This year, the police are using rakes to search a parcel in Hanover where evidence was removed from a vegetable garden that was once inhabited by Brücker
Brueckner made a living doing odd jobs in the area Madeleine had disappeared into and was also known to have broken into hotel rooms and vacation homes.
Weeks after the allocation search, authorities said they had been looking for digital storage devices, but Brueckner's attorney accused them of "desperation".
Since taking the lead in the case earlier this year, German police have made efforts to explain what evidence they have of Madeleine's disappearance.
Last week, a leaked memo revealed that Portuguese investigators were "shocked" by the lack of concrete evidence after being briefed on the Brueckner case.
Previously, there was confusion over whether the German authorities had concrete evidence that Madeleine was dead, as they had originally suggested.
Madeleine's parents, Kate and Gerry McCann, have declined to receive a letter from German investigators saying Madeleine was dead.
German prosecutor Hans Christian Wolters, who heads the German investigation into Madeleine's disappearance, said a letter had been written to the couple but would not reveal what it said.
In July, police officers were seen carrying large blue bags away from a German parcel that was once known to frequently abduct suspect Christian Brueckner
City police are continuing their active investigation into Madeleine's disappearance. Operation Grange is an investigation into a missing person as there is no “definitive evidence that Madeleine is alive or dead”.
The Portuguese authorities are also continuing their investigation and searched a number of wells in the Algarve earlier this month.
Brueckner is currently in jail on a drug abuse conviction and is still on trial for raping a 72-year-old American woman in Portugal in 2005.
In September, a European court rejected an appeal he had lodged against his extradition from Italy to Germany in the drug case for procedural reasons.
As a professional criminal, he was identified as the new prime suspect in June after German police released a series of new pieces of evidence, including details of his cars and phone numbers, and urged people to provide new leads.
This week it turned out that the 43-year-old was injured during a probation hearing in Braunschweig.
The court in Braunschweig said he had injured his ribs when police officers put ankle shackles on him before the hearing on Monday.
The court said he had been hospitalized and the parole hearing had taken place. He later returned to prison.
