The state government had nothing to do with it now, since the case was sub-judice, she said.
The minister was replying to CPI-M member Anisur Rahaman's query about why the culprits in the case were not punished even after two years.
On June 7, 2013, a 20-year-old college student was allegedly abducted, gangraped and murdered in Kamduni, near Barasat, about 20 km from Kolkata.
She told the members that many such incidents had taken place during the erstwhile Left Front rule.
