German police investigating the disappearance of Madeleine McCann have searched a garden plot in Hannover in connection with their probe, prosecutors said.
Julia Meyer, a spokeswoman for the prosecutor's office in Braunschweig confirmed local media reports that police investigators had been at the site since Monday with an excavator in connection with the case.
"The procedure is taking place in connection with our investigation regarding Maddie McCann," she told The Associated Press.
Ms Meyer said she could not give any further details on the procedure, adding only that police would "still need some more time to finish".

The suspect, who is currently in prison in Germany, spent many years in Portugal, including in Praia da Luz around the time of McCann's disappearance, and has two previous convictions for "sexual contact with girls", authorities have said.
Authorities have not released the suspect's name, but he has been widely identified by German media as Christian B.
He was last registered as living in Germany in the city of Braunschweig, which is about 40 miles from Hannover.
