Man Arrested in British Family's Murder in the Alps

Suspect is brother of one of the victims

Police in Britain have arrested a man on suspicion of conspiracy to murder a British family of Iraqi origin who were killed in a high-profile murder in France last year, French public prosecutor Eric Maillaud said on Monday.

Saad al-Hilli, an Iraqi-born British engineer, was found shot dead in September 2012 with his wife and mother-in-law in their BMW car on a remote mountain road near the village of Chevaline, with the body of a cyclist, Sylvain Mollier, discovered nearby.

They were killed in what appeared to be execution-style murders, with at least two hits to the head from a semi-automatic pistol.

Speaking to Reuters, Maillaud identified Saad al-Hilli's brother Zaid as the man arrested.

"Several lines of questioning closed over time… The main theory today is linked to the family," he said.
