Guwahati, Nov 27 (IANS): Police in Assam Wednesday said a woman whose death sparked widespread protests was not raped.

Superintendent of Police P.K Bhuyan ruled out the "rape" angle and said the woman died due to severe head injuries in Lakhimpur district.

"I am yet to physically receive the post mortem report. However, my officers who are in Guwahati obtained the post mortem report today (Wednesday), which ruled out any rape angle. The woman died due to severe head injuries," Bhuyan said.

Police recovered the woman with multiple injuries from near Boginadi police station in the district Friday. The woman later died at a hospital in Guwahati.

Local people and organisations have taken to the streets of Lakhimpur town since Sunday, terming the incident as a rape and murder.

They protested against the failure of police to identify and arrest the culprits.

Some of the agitating organisations have even compared the incident with Dec 16 gang rape in Delhi last year.

Police said they could not record the statement of the victim as she was not in a position to speak.

"It's a incident of crime and we have registered a case in this regard. Investigation is on to find out the culprits. It could be a planned murder or an accident," Bhuyan said.
