Kolkata, Nov. 9 -- A team from Delhi Police visited former West Bengal Chief Minister Mamata Banerjee's Kalighat residence on Monday to serve her a notice in connection with a 13-year-old criminal case.

Issued under Section 160 of the CrPC, the notice requires Banerjee to join the investigation as a witness, not an accused.

The case relates to an incident on April 9, 2013, when Banerjee, then Chief Minister, and the state's Finance minister Amit Mitra were surrounded and heckled by SFI activists during a demonstration outside the erstwhile Yojana Bhawan in New Delhi.

The protest escalated into violence, during which Mitra was assaulted and required medical attention. Following the incident, Delhi Police registered a case at Parliament Street Police Station.
