News comes in that the French police have put Jerome Kerviel's assistant under investigation:

He is accused of "knowingly helping Jerome Kerviel to record fictitious operations" at the bank in 2007 and early 2008. The filing gives officials times to investigate and later decide to drop charges or go trial...
Investigators have already filed preliminary charges against Kerviel for forgery, breach of trust and illegally accessing the bank's computers.
An internal investigation by SocGen released to the public in May said it found "signs of internal complicity" by Mougard.
