Also just in from Yves, they caught the Arak bandits:
"Two people from Tam and In Salah I contacted told me that the bandits from
the Arak incident had been idenified (and presumably been caught). They were
called to be "normal" people, not fundamentalists, from the In Salaha region
and well known by locals and the gendarmerie.
The contact in Tam mentioned that the tourist had contact with the bandits
some days before the ambush and were informed about the itinerary. In fact
they first attacked the tourist car and only then stopped local cars,
probably for logistical reasons (fuel!)."
Moral: as in Agadez, be careful who you talk to and tell of your route...
