Madeleine Suspect Quizzed For Second Day
Portuguese police are questioning a suspect in connection with the investigation into the disappearance of Madeleine McCann for a second day.
Sky News' Crime Correspondent Martin Brunt said the suspect is one of four "persons of interest" being investigated.
A further eight potential witnesses are also being quizzed.
Scotland Yard is sitting in on the interviews, which were initiated by Portuguese authorities on Tuesday.
The first suspect has been named as Russian-born businessman and IT specialist Sergey Malinka, who is 30 years old.
He was spoken to as a witness, rather than a suspect, in the early days of the investigation.
There is allegedly a forensic link between his apartment and the McCanns' apartment in Praia de Luz, where Madeleine vanished shortly before her fourth birthday in May 2007.
In an interview with Sky News at the time, Mr Malinka strenuously denied any involvement.
Sky's Martin Brunt said additional evidence thought to be against him includes a conversation overheard near his apartment shortly after Madeleine's disappearance which police think is suspicions.
His car was also found burned out a year later and somebody had written the word "Speak" on a wall near his home.
Police have also quizzed a 38-year-old former employee of the resort where the McCanns were staying who is suspected of carrying out burglaries around the holiday complex.
The third suspect is a 50-year-old man reported to suffer from a mental health disorder who was reported to have been acting strangely when Madeleine went missing.
The fourth man being quizzed is another burglary suspect, aged 23, who is thought to have been a beggar in the area. He reportedly made a number of suspicious phone calls at the time.
It has not been revealed which of the four suspects was being questioned on Wednesday.
The interviews form the latest phase of the Scotland Yard probe on the ground in the Algarve.
Portuguese and British investigators excavated an area of scrubland to the west of the resort at the start of June but found no evidence related to the case.
