Police investigating the murder of a British satellite engineer gunned down in the French Alps along with his wife and mother-in-law have released an image of a male motorcyclist they want to speak to.
The French Gendarmerie have released an artist's impression of a motorcyclist they are trying to trace who was seen riding in the area between 3.15pm and 3.40pm on the day the murders took place.
They are appealing for who anyone who might recognise the man in the image to come forward.
50 year old Saad al-Hilli from Claygate in Surrey, his dentist wife Ikbal and her elderly mother Suhaila al-Allaf were murdered on a remote forest road near Lake Annecy in southern France on September 5, last year. French cyclist Sylvain Mollier was also killed.
Iraqi-born Mr al-Hilli's eldest daughter Zainab was shot, beaten and left for dead, but survived. Her four-year-old sister Zeena lay hidden under her mother's corpse and was only discovered eight hours after the murders.

(Charlie was) a talented and very motivated boy who made a huge impact on the lives of every one who knew him.
He was a popular boy and threw himself into school life with 100% effort.
Charlie loved a wide range of sports and especially the great outdoors.
He will be hugely missed and we send our thoughts and prayers to his family, especially his mother and sister, at this tragic time.
Zainab Al-Hilli's state of health is understood to have improved in recent days, allowing her to travel back to the UK.
– A police source in Annecy
Zainab left France this morning at around 8am. Police from Britain accompanied the little girl.
Her departure follows that of her younger sister, Zeena, who returned to the UK last week after escaping the brutal attack unscathed. The four-year-old survived by cowering under her mother's skirts but she was only discovered eight hours after the killings.
Surrey Police have confirmed that Zainab Al-Hilli is returning to the UK on Friday.
A schoolgirl whose parents and grandmother were gunned down in a shooting spree in the Alps has left France, sources have said.
Zainab al-Hilli, seven, was placed in a medically induced coma after she was shot in the shoulder and badly beaten in the massacre which killed her three relatives last week.
The child, who is seen as one of the key witnesses in the case, left hospital at about 8am on Friday, accompanied by British police.
An RAF cyclist has described the moment he stumbled upon the site of the French Alps massacre last week.
Brett Martin told the BBC that he initially thought there had been a terrible accident, as he found a little girl "stumbling" around, bleeding and "moaning" in a secluded car park close to Lake Annecy.
Next to her was a BMW, it's engine still revving and its wheels still spinning, inside which lay the bodies of Saad al-Hilli, 50, his dentist wife Iqbal, 47, and her mother.
A fourth body, that of Sylvain Mollier, 45, the French cyclist who apparently stumbled across the attack, lay on the ground.

The chief prosecutor in the area of the French Alps where three Britons were gunned down, is expected to visit the al-Hilli family home in Claygate, Surrey, this afternoon.
It's part of Mr Maillaud's 24-hour trip to the UK and he will also meet police officers and Crown Prosecution Service officials.
