A motorcyclist sought by police investigating the murders of three members of a Claygate family in the French Alps has been found and ruled out of the enquiry, according to reports.

The biker was traced last month, two years after the shooting of Saad Al-Hilli, 50, his wife Iqbal, 47, and her mother Suhaila Al-Allaf, 74, near to Lake Annecy on September 5, 2012.

Authorities have said the man, from Lyon, had no connection with the killings and was in the area by accident when they took place.

From September 2014: Al-Hilli killers may have got away with the perfect crime, says French prosecutor

According to a police interview given to French radio station France Info, he was interviewed by detectives from Chambery and told them he came to the area of Chevaline to practise hang gliding.

The motorcyclist was said to have been driving on the road at about 3pm before being told by two forest rangers to leave. He agreed and drove back down the path past the car park where the family from Oaken Lane were killed.

An investigator told France Info: "His personal and professional profile exclude him 95 per cent from the list of suspects but further inquiries are still required."

The motorcyclist said he did not make the connection between him being near the scene and the identikit picture of him circulated by police in November 2013.

Mr Al-Hilli's brother, Zaid, 54, of Bray Court, North Parade, Chessington, was arrested on suspicion of conspiracy to commit murder in July 2013 but was released without charge in January 2014.

Two other people have been questioned about the deaths but released without charge.

The two Al-Hilli children, both former pupils of Claygate Primary School, survived the attack.

Zainab, then seven, was shot and pistol whipped by the gunman, and Zeena, then four, escaped unharmed after she hid beneath her dead mother's skirt.

A French cyclist, Sylvain Mollier, 45, was also shot dead in the attack.

In an inquest into the deaths in November of last year, Coroner Richard Travers said it was "beyond no doubt" that Mr Al-Hilli, his wife and his mother-in-law were unlawfully killed while on holiday.
