Roads leading into the Arade Dam, the little paradise of sole suspect Christian Brueckner a 40-minute drive from Praia da Luz where the youngster vanished 16 years ago, were sealed off yesterday.
Police put a remote Algarve reservoir on lockdown this morning as they got ready to comb scrubland near the water in the first major search for Madeleine McCann in nine years.
The first major search for Madeleine in nine years comes after German police discovered photos of prime suspect Christian Brueckner at the Barragem do Arade reservoir.
