Kolkata: Maoists released police officer Atindra Nath Dutta Thursday evening, almost three days after they had kidnapped him from a police station in West Bengal, an official said.

The Maoists had threatened to kill Dutta, who was abducted by the Leftwing ultras early Tuesday during an attack on Sankrail police station in West Midnapore district.

Earlier Thursday, a West Bengal court released 14 tribal women, which was one of the conditions laid down by the Maoists for the release of Dutta.

The West Midnapore district court released the 14 tribal women, who were earlier arrested by the police for allegedly having links with the Maoist ultras in Lalgarh region.
