NEW DELHI: A prosecutor , who had scrutinised the charge sheet in the Rs 100-crore transport scam, has accused Rajendra Kumar , principal secretary to Delhi Chief Minister Arvind Kejriwal , of pressurising him not to finalise the report or face suspension.In his letter to Joint Commissioner of Police of Anti- Corruption Branch M K Meena, prosecutor Vinod Kumar Sharma said he was called by some senior officials of Delhi secretariat , including Rajendra Kumar, and pressurised by them to bring before them the file of the charge sheet before finalising it.It is pertinent to mention that recently Rajendra Kumar and other top officials in Transport Department were summoned by Delhi government 's Anti Corruption Branch (ACB) in connection with the scam.The ACB had yesterday filed its charge sheet in a Delhi court naming nine persons, including two IAS officers, as accused in the case. Special Judge Poonam Chaudhry has fixed September 26 for consideration on the charge sheet.Seeking his withdrawal from the case, the prosecutor said he was unable to bear the pressure put on him and do justice with the case and alleged that Delhi Government was trying to delay the matter.Sharma, in his letter to Meena, said "It is respectfully submitted that scrutiny of challan (charge sheet) of the case .... was done by me on September 1. Today (September 2) I was called by some senior officials of Delhi Secretariat. I was pressurised by them, who are alleged (suspect) in the case, i.e. Rajendra Kumar, secretary to CM of Delhi"."They directed me to produce the file before them before finalisation," Sharma said, claiming he was threatened to be suspended if he did not obey the orders of the officials."I am a sick person of high blood pressure, I am unable to bear pressure and to do justice in the case. I may be allowed to withdraw myself from the case," the prosecutor said in the letter. His prayer is yet to be accepted.
