Kolkata: West Bengal Chief Minister Mamata Banerjee in Nandigram demanded a high- level probe into the incident, insisting the inquiry by election observers lacks credibility.

Election Commission concurred with the reports sent by its two special poll observers and the state government that there was no pre-meditated attack on the TMC supremo, said the election commission on Sunday.

The Superintendent of Police of Purba Medinipur Pravin Prakash was also suspended, while District Magistrate Vibhu Goel was transferred. “It is a welcome move that the EC has removed the officials over security lapses. At least they have taken some action, said Chief Minister Mamatha Benarjee.

Benerjee was using an ordinary vehicle, her director of security Vivek Sahay was in a bulletproof car when the incident took place. Also, no approval was taken from the returning officer of the area where the incident took place, said the sources.
