Where's Delta bursary fraud whistleblower, Ambrose Ezewani?

I picked this up on linda ikeji blog and I felt its worth your reading and your reaction for as the saying goes "evil triumph when good men refuse to speak out".

It's easy for us all to move from this because this dude is not related to us or even someone we know personally...but if we as youths of this country keep quiet, this will continue to happen, and next time it could be you or me, or someone close to us.
The ex student of the University of Lagos and former President of the National Association of Delta State students, UNILAG chapter, was picked on Monday April 28th in Lagos by officials of the Delta State government after he blew the lid on a systematic student bursary racketing allegedly happening in the state. (In case you missed it, read here).
His friends say Ambrose hasn't been heard from since he was picked up last week. Where is he?
