As drama continues in West Bengal over an unexpected visit of the CBI officers to Kolkata, the central agency dragged the state government to the Supreme Court today. The SC will now hear the CBI case tomorrow. CJI says if the CBI lays a single piece of evidence or any material to show that any authority in WB or any police officer is engaged in tampering of evidence in the chit fund scam, we will come down so heavily on them that they will regret it. Remember high drama unfolded in Kolkata last evening when Chief Minister Mamata Banerjee decided to go on an indefinite strike to "save the constitution."
