Two men have been arrested regarding the Zotob PnP worm case.
Moroccan authorities arrested "Diabl0", aka Farid Essebar and Turkey authorities arrested "Coder", aka Atilla Ekici. The suspects are aged 18 and 21, respectively.
Both nicknames can be found from the code of Zotob.A: the worm connected to a irc server named "diabl0.turkcoders.net" and contained the words "Greetz to good friend Coder".
Diabl0 is most likely associated with some of the Mytob variants too.
