The incident happened on August 21, a day after the killing of five NDFB(S) terrorists at Dwimuguri by a joint team of Assam Police and the Indian Army.
Police said the body was retrieved at least 24 hours after she was killed and blamed the remote location of the village and non-cooperation by villagers for the delay. The girl was dragged out of her house, beaten up and shot at point blank range at least nine times.
The girl was reportedly shot nine times in the presence of her parents
State government sources said an inquiry would be made to verify the claims that the victim's body was lying in a field in the village for two days. The government also said it would start a bravery award after the girl's name.
Assam Chief Minister Tarun Gogoi announced Rs 20 lakh ex-gratia for the victim's kin and also recommended her name to the central government for the National Bravery Award.
The chief minister also directed the police to launch a manhunt to arrest the killers of the girl who was a student of Standard IX.
