The case triggered public anger and demonstrations demanding better safety for women, after which Mamata Banerjee visited the home of the dead student.
Six people were today convicted for the gang-rape and murder of a 21-year-old college student in West Bengal's Kamduni. Two other accused in the case were acquitted.
The court will pronounce the sentencing tomorrow.
Ahead of a verdict protesters clashed with the police outside a court in Kolkata. The protesters are members of the student wing of a Left party.
In June 2013, a college student was abducted on her way home from class, taken to an isolated factory compound where she was gang-raped, and then killed in a village in Kamduni, about 30 km from Kolkata. Her body was found that night by her brother in a canal.
The case triggered public anger and demonstrations demanding better safety for women, after which Chief Minister Mamata Banerjee visited the home of the dead student; she controversially accused demonstrators during that visit of having communist and Maoist links, provoking a backlash and a new wave of protests.
Eight men have been charged with the rape and murder; a ninth suspect died in jail during the trial.
