Kolkata, Sep 13 : Enforcement Directorate (ED) in CGO complex in Salt Lake here has been wrapped under thick security blanket since early Wednesday as Trinamool Congress leader Abhishek Banerjee is scheduled to appear for interrogation in connection with the multi-crore cash-for-school job case in West Bengal. A huge police contingent led by an officer in the rank of assistant commissioner of police has been deployed to man the security outside the CGO complex. The security has been tightened within the CGO complex as well with additional central armed forces personnel being deputed there compared to that of normal working days. The authorities are also acting strictly on entry within the CGO complex and no one is allowed to enter without producing either an identity card or papers substantiating the reason for entry. As per information available so far, Banerjee is expected to arrive at the central agency office any time between 11 A.M. and 11.30 a.m. On Tuesday evening, West Bengal Irrigation and Waterways Department Minister Partha Bhowmik gave a clear indication of Banerjee going to the ED office instead of attending the first coordination committee meeting of the grand opposition bloc INDIA alliance at New Delhi. "You will see tomorrow that Abhishek Banerjee is not afraid to face any kind of investigation. He is a man with a strong spine unlike the leader of opposition, Suvendu Adhikari," Bhowmik said on Tuesday evening. On Tuesday, ED also gave a verbal assurance to Calcutta High Court of not adopting any coercive action against Banerjee till the final judgement on his petition to expunge his name from the central agency probe in the school job case is delivered. The final hearing in the matter is scheduled on September 19 by the Calcutta High Court's single- judge bench of Justice Tirthankar Ghosh. /IANS
