Kolkata, March 26 (ANI): One suspect in the elderly nun gang-rape case was arrested by the Crime Investigation Department of India (CID) in Mumbai on Thursday. This is the first arrest in the case, although nine people have been detained by the police so far. On Monday, the National Commission for Women had condemned the West Bengal government for no arrests in the case even a week after the incident. West Bengal Chief Minister Mamata Banerjee had last week decided to entrust the investigation of the case to the Central Bureau of Investigation, which had sparked various protests from the Christian community, who questioned their safety in the country.
