British police will spend a fourth day carrying out investigations on an area of scrubland close to where Madeleine McCann went missing in Portugal seven years ago.
Officers, accompanied by their Portuguese counterparts, were expected to probe the area in Praia da Luz on the Algarve until Friday but have applied to spend an extra seven days there.
Police have shifted their investigation from the centre of the town where Madeleine McCann went missing to an area of scrubland a mile away.
Madeleine McCann search police are focusing on an area where ground-penetrating radar equipment has picked up an image beneath the soil.
Seven years on from Madeleine McCann's disappearance, British detectives are in Portugal to meet with police.
