KOLKATA: The CID has managed to convince the 7 1-year-old Ranaghat rape survivor to give a confidential statement in court — which could be the clinching evidence in the case. The nun has agreed to testify in Delhi, rather than in Bengal, and the state CID readily accepted it. The breakthrough came after CID officers visited the mission and talked to the nuns on Thursday. The agency is moving a Delhi court and her statement may be recorded as early as Monday, said CID sources.It’s not necessary for the statement to be recorded in the court where the trial is on, said advocate Milon Mukherjee, adding that a metropolitan magistrate or judicial magistrate may take her statement. Sources said CID will also seek a blood sample from the nun, a legal necessity.President of CBCI (Catholic Bishop's Conference of India) Cardinal Baselios Cleemis Thottunkal after visiting Ranaghat Sub-divisional hospital and the injured nun in Nadia district, meet CM Mamata Banerjee in Nabanna (Howrah which houses the temporary State Secretariat of West Bengal) on Wednesday afternoon. photo by sajal mukherjee. (TOI Photo)CID sees the nun’s statement as a major breakthrough even as it closes in on fugitive suspect Milan Sarkar, a Bangladeshi criminal alleged to be the leader of the cross-border gang that raided the Ranaghat convent. According to sources, CID has proof that Milan was in India till three days after the crime. He was in constant touch over two key gang members — Habibul and Aslam. Tracking Milan’s call details from the cellphone record of alleged rapist Md Salim, CID believes Milan stayed back to ensure that everyone escaped back into Bangladesh.READ ALSO:CID believes Habibul could actually be one of those who raped the elderly nun. A CID team has reached Ludhiana and taken custody of two Bangladeshi suspects. One of them is Md Habibullah, who CID suspects to be Habibur. The state agency has spoken to CBI and will move court for lookout notices against at least four of the accused who have escaped into Bangladesh using genuine passports. Once the orders come through, Interpol has to be brought into the picture.Sources said that the father-in-law of Salim is an influential member of a political party in Bangladesh. Whenever Bangladesh law enforcement stepped up the heat on Salim or his gang, this leader arranged for them to sneak into India, say sources. CID will brief central agencies on this soon.Ludhiana police wants CID to question Zeenat Sheikh, who allegedly acted as a “facilitator” for the Bangladeshi gang. Punjab Police say they have proof that she had been receiving money regularly from Nadia. Ludhiana ADCP-crime Mukhwinder Singh said, “All of them are members of a gang and claim to be residents of Bengal. But the addresses they gave are false. They all illegal immigrants from Bangladesh and two of them — Md Salim and Habibul — have links with the nun rape case.” Bengal Police had sent photos of the accused in the rape case and two of them match with Salim and Habibul, he added.The CID, however, is cautious. “We are not sure if anyone detained in Ludhiana has a direct link. But we hope they have knowledge on those who attacked the convent,” said a senior officer.
