Body of one Sunita Murmu was recovered from a drain on Friday morning in Pub Dabra village in Kokrajhar district.
The deceased was a Class IX student and originally hailed from Runikhata.
She was allegedly in a relationship with one Nerswan Kumar Tudu- a resident of the same village.
Villagers informed that the girl got pregnant and she was living with Tudu at his residence since July 19. Later, the child was aborted.
Things, however, were not fine and villagers informed that Murmu and Tudu often indulged in a quarrel and that there were numerous other domestic issues in the house.
“Sunita went missing on August 18 and today her body has been recovered from a drain. This is a pre-planned murder,” alleged a relative of the dead girl.
The police have not said anything as of now and the body has been sent for post-mortem.
