Madeleine McCann: Police probe 18 intruder break-ins

British police investigating Madeleine McCann's disappearance are now looking at 18 potentially linked break-ins by a lone intruder into Algarve villas.

Six have come to light since an appeal by UK detectives last month, with five involving alleged sexual assaults against young British girls.

Naomi Grimley told BBC News one of those attacks was in the same resort from which Madeleine vanished in 2007.
