The Superintendent of police, Ashwini Kumar Sinha, told PTI that an 11-member team of an NGO had gone to the village to perform a street play on migration and human trafficking on Tuesday.

The National Commission for Women (NCW) has formed a three-member inquiry team who would go to Khunti district in Jharkhand to look into the case involving gang rape of five women, the NCW chairperson said.
The situation took an ugly turn after a group of men arrived at the sport and took the team to a nearby forest at gunpoint. They were performing a play at RC Mission School in the village, which is located 90 kilometres away from Ranchi. They also said that the sexual assault was filmed to be used as leverage by their captors to prevent them from reporting it to authorities. The DIG, however, appealed to the media to report to the police if they come across any video regarding the incident.
Police officer Rajesh Prasad added that the women were working for Asha Kiran, an NGO supported by Christian missionaries.
They filed a police complaint on Wednesday.
