A French investigator's flown to London to interview the brother of a British man who was killed - along with his wife and mother-in-law ... and a French cyclist - in the Alps.

He says Zaid al-Hilli's been to a police station to deny there was a feud with Saad about money - one of the leads officers were following.

The dead man's 8 year old daughter remains in a coma after also being shot - while police say her 4 year old sister couldn't provide many details about what happened.
