French police investigating the killing of a British family in the Alps in 2012 have arrested a 48-year-old man, reports the BBC.
The man, from the Haute-Savoie region, has been placed in formal custody.
He was detained after the publication in November of an identikit image of a motorcyclist seen near the scene of the murders in a car park near Lake Annecy.
Saad al-Hilli, an Iraqi-born British citizen, had been found dead in his BMW car; his wife Iqbal, her mother and a French cyclist were also killed.
Mr and Mrs al-Hilli's two young daughters survived the attack.
The body of the cyclist, Sylvain Mollier, was found nearby.
Mr al-Hilli and his family lived in Claygate, Surrey and were on holiday at the time of the attack.
More than 100 police officers in France and the UK have been involved in investigating the case and about 800 people have been interviewed.
