Madeleine McCann search: Abandoned buildings examined as ground radar may be deployed

Day two in the search in Portugal's Algarve region for clues to where Madeleine McCann is - and there are pockets of police activity dotted around the vast scrubland.

From where I'm standing, I can see three searches under way, all in abandoned buildings.

To our right, police are using chainsaws to cut down a tree that's grown inside a derelict barn.

Latest updates from the search

Ahead of us, officers in white hard hats empty rubble from inside another dilapidated building.

To the left, a team of three lift stones through the window of an old stone hut.

It's thought that ground radar equipment may then be used to scan the floors.

As we walk through the brush, the ground is dry and hard.

'Nothing has been found'

Digging here is hot, exhausting work - but so far, there is no news.
