PORTUGUESE cops 
							failed to probe a possible sighting of Madeleine 
							McCann's abductor near her family's holiday 
							apartment, police case files reveal. 
							Babysitter 
							Margaret Hall was looking after a little girl in the 
							flat eight months before the McCann's arrived. 
							
							When she 
							investigated a noise outside, she saw a shoe in the 
							shadows. 
							
							She 
							cried out and a man stepped out shouting, 'No, no'.
							
							
Margaret said he 
							was almost certainly Portuguese. 
							She told 
							detectives she returned to the apartment 'in a state 
							of shock'. 
							
							
							Couple 
							
							But police 
							regarded the incident as 'outdated' as it occurred 
							so long before Maddie went missing, their 
							20,000-page dossier shows.
