Kolkata tightens security to prevent protesters demanding justice for rape victim.

Tight security was implemented in Kolkata and Howrah on August 9 to prevent protesters from reaching the state secretariat during the 'Nabanna Avijan' march, marking the one-year anniversary of the R.G. Kar rape and murder case. The police set up barricades and restricted traffic, aiming to prevent the march. Protesters, determined to demand justice for the victim, attempted to breach the barriers despite police warnings. The Central Bureau of Investigation's probe into the case continues.
