'Blood clue' in Madeleine inquiry

BBC News report; says 'Forensic tests are being carried out on suspected traces of blood found in the apartment where Madeleine McCann was last seen on 3 May, the BBC has learnt. It is understood the find was made during a search - with at least one British sniffer dog - of the McCanns' now-vacant apartment in Praia da Luz. If tests confirm the find, police will look for a DNA match with Madeleine. It is believed detectives returned to the McCanns' holiday apartment last week with at least one highly-specialised sniffer dog from Britain. Inside, they found traces of what is thought to be blood but investigators cannot be 100% certain, a Portuguese police source told BBC News.'
