Disgraced former Portuguese police chief Goncalo Amaral has branded the new Madeleine McCann searches over the top and wheeled out a sick theory about her disappearance.

The ex-detective, who was sued over a 2008 book about the 18-year-old mystery in which he wrongly pointed the finger at the missing youngster's parents, also accused his own former police force of 'connivance' with 'shoddy' German cops in a foul-mouthed blast 24 hours after the start of a fresh operation to find Maddie's body.

Amaral, thrown off the Madeleine investigation in 2008 after publicly criticising British police involved in the case, revealed his theory to Portuguese daily Correio da Manha.

He claimed of the fresh searches that are taking place near suspect Christian Brueckner's old cottage close to the Algarve holiday resort of Praia da Luz where Madeleine vanished on May 3 2007 as her parents Kate and Gerry ate tapas: 'This much wasn't needed.

'A plane with geo-radar would have been enough and reduced the search area.'
