Days after the alleged gangrape on a 71-year-old nun in a Christian missionary school in Nadia district, West Bengal police are yet to make any headway in the case that has left the nation shocked.

Police on Sunday however detained eight people including a man resembling a suspect seen in CCTV footage from the convent in Ranaghat city of the district with large concentration of Christians. Police have refused to name the detained as suspects.

They say that they are still verifying if one of them, a resident of Nadia, is from the gang of the rapists in the Ranaghat school, about 200 km from Kolkata.

The police were sharply criticized for not acting on a complaint lodged by the school authorities after some threat calls a week ago.  People pointed out that police are yet to locate the caller who had threatened the school principal even as no policeman was posted at the school despite a request for security at the school.

Locals are furious with the way police handled the situation as no suspect has been arrested after about a dozen armed men raided the Christian missionary school Saturday, allegedly raped the nun and assaulted two others.

People reminded the media of the alleged suspicious role Nadia Superintendent of Police “Arnab Ghosh had played” in the infamous Saradha scam as the chief of the detective department of the Bidhannagar police commissionerate.

Enforcement Directorate, which probed the major financial scam in West Bengal, alleged Ghosh of not cooperating in the investigation. He was later transferred to his current position in Nadia.

People expressed their anger alleging that police are still beating about the bush over the alleged school gang rape. They raised question over police&’s failure in identifying the suspects despite the CCTV footage.

School authorities have claimed that the nun was raped as she tried to prevent the attackers from looting the money from the school chapel. But police say the attack was related to an old rivalry.

“If the crime was an outcome of an old rivalry the criminals wouldn’t have targeted Mother Superior. It seems they mistook her for the person for whom they were actually engaged to treat a lesson,” a police officer said, speaking on condition of anonymity because he was not authorized to speak to the media.
