Kolkata, July 27 (TIWN) The Central Bureau of Investigation has summoned Trinamool Congress Rajya Sabha MP Derek O'Brien in connection with the probe into the Saradha chit fund scam, a CBI official said on Saturday.

The agency had summoned him in January too but he sought time, citing the ongoing Winter Session of Parliament, they said.  The officials said the quizmaster-turned-politician may be questioned about some financial transactions noticed by sleuths in the bank accounts of TMC mouthpiece 'Jago Bangla'.  O'Brien is the publisher of the party's official newspaper.
