New Delhi: The Supreme Court, on Friday, refused to entertain a petition seeking a CBI investigation into the alleged incident at Nandigram in West Bengal, which left the state Chief Minister, Mamata Banerjee injured on March 10. While hearing the matter, a three-judge bench headed by Chief Justice of India SA Bobde said that the petitioner can go to Calcutta High Court.The plea had also sought directives to issue guidelines for investigation of similar incidents which may affect the Electoral machinery in future. The PIL, filed through Advocate Vivek Narayan Sharma sought directives to create a temporary body with powers to look into the incidents of violence in the run-up to the West Bengal elections. The plea also sought a CBI probe, claiming that the 'alleged attack' was against a person holding a constitutional post and could hamper the voters' confidence in the electoral machinery.West Bengal Chief Minister Mamata Banerjee was injured in an incident, alleged as 'attack' on her by the Trinamool Congress. The party had approached Election Commission seeking a probe into the matter and claimed that 'BJP' was behind the 'attack'. “On March 9, the Election Commission changed the state Director General of Police. On March 10, a BJP MP posted on social media – ‘aap samajh jayenge, 5 pm ke baad kya hone wala hai’ and it happened to Mamata Didi at 6 pm. We condemn these incidents and this kind of behaviour, and want the truth to prevail,” TMC MP Derek O’Brien had said after the incident.The BJP had rubbished the claims and said that the claims were an attempt by the TMC to gain sympathy. BJP president JP Nadda had said that there was a discrepancy in the claims made by Banerjee immediately after the incident and, in the video released from the hospital the next day.
