New search at McCann suspect home

Up to 10 officers returned to the home of the only official suspect in the case, in Praia da Luz, in the Algarve.

Four-year-old Madeleine went missing from the resort in May, while she was on holiday with her family.

Mr Murat's property was initially searched days after Madeleine was abducted while she slept.

The BBC's Steve Kingstone, in Praia da Luz, says police - including two British detectives - arrived at the house at 0700 (0600GMT).

He says the property is thick with vegetation and the officers are using rakes and hedge trimmers to clear the search area.

'Sighting'

Mr Murat, who is with his lawyer, was not arrested.

He was declared a suspect 10 days after Madeleine was last seen, on 3 May, but has strenuously denied any involvement in her disappearance.

Mr Murat's house is about 100m (330 ft) from where Madeleine's family was staying.

He has been told the search will take up to four days.

The search comes as police investigate a possible sighting of Madeleine in Belgium.

Detectives have issued a sketch of a Dutch man and an English woman seen with the girl in a restaurant in Tongeren on the Dutch border.

A customer at the restaurant said she was "100% sure" she had seen the four-year-old.

Madeleine's parents Gerry and Kate McCann have also travelled to Spain to mark the three months since her abduction.
