Calcutta, May 28 :     Police have reopened investigation into the case of the missing Calcutta University assistant controller of examination Manisha Mukherjee. Mukherjee disappeared in September 1997, leaving behind a trail of questions which showed up many CPM leaders in poor light. The investigation, which had literally been closed for want of clues, is being reopened after some photographs of Manisha were recovered from a box in her house by her mother. Deputy commissioner, detective department, Narayan Ghosh said Manisha?s mother Chinu Mukherjee recently met him with an envelope containing 30 pictures of Manisha with colleagues like former controller of examination Gopal Banerjee. Banerjee is seen with a woman in some of the pictures. ?There is a photograph of a woman with a shaven head. We are not sure whether it is Manisha,? Ghosh added. He said a team of detectives will leave for Ayodhyay hills in Purulia shortly. ?We have received information that there is an ashram in Purulia owned by Banerjee where Manisha may be found,? he added. Purulia superintendent of police Adhir Sharma said a team from the Bagmundi police station will scan Ayodhyay hills tomorrow. ?Small ashrams exist there, but I am not sure whether any among them belongs to Banerjee. I have sent officers to check,? Sharma said over phone from Purulia. Manisha was supposedly close to several influential CPM leaders. When she disappeared, it was alleged that the university authorities were trying to victimise her for disobeying the orders of a section of CPM leaders. The party had allegedly asked her to do some unlawful acts, violating the university?s norms. Before she went missing, Manisha was transferred to the university?s history department as a lecturer. When she failed to teach properly, it was alleged she was suffering from depression. She was later shifted back to her old department, but failed to rejoin it. Nazrul Islam, the then deputy commissioner, detective department, led a team of detectives to track Manisha. They made little progress. Sources alleged that influential CPM leaders had stonewalled investigations. Police had earlier been told that Manisha might have embraced Buddhism and could be in Bodh Gaya. There was another theory that she was recuperating in a mental asylum. But investigations led the police to nowhere. Chandanpur overbridge Eastern Railway today said agitated residents were preventing officials from carrying out repairs to Chandanpur station?s damaged foot overbridge, forcing passengers to cross the tracks to reach the other platform, which was hazardous. The residents went on the offensive after Shrabanti Banik fell off the stairs on May 20 and injured herself. When officials went to the spot for repair work, the locals demanded that every concrete slab be replaced, irrespective of the condition. The assurance that it would take some time was not accepted by the residents who have since been obstructing work.
