An al-Qa'ida member comes in from the cold

I don't know anything about Fawwaz al-Otaibi who was wanted by KSA since February and who, some time between then and now, returned to KSA to surrender. But I'm curious about where he was immediately before he packed it in. Riyadh isn't saying. The February hotsheet, naming 83 Saudis and 2 Yemenis, says that al-Otaibi's last known location was in Iran. That could mean that he had entered Iran openly, at a border station or airport. But was he en route to some other place, such as Pakistan? If anybody knows, get in touch please.
