Commemoration Day was observed at the state police headquarters here, with top officials paying respect to over 300 policemen 'martyred' in the last one year. Director General of Police TK Rajendran honoured the martyrdom of 370 policemen killed between September 1, 2016 and August 31, 2017 by placing a wreath at the police headquarters here.

Former Governor of West Bengal M K Narayanan, officials from the three armed forces stationed here, members of state police force, City Police Commissioner A K Viswanathan and others also placed wreaths on the occasion, a police release said.

A traditional gun salute was also given to the police martyrs, it added. Commemoration Day is observed to pay homage to 10 Indian policemen martyred in firing by Chinese troops in 1959 and 34,400 others who laid down their lives protecting India's unity.

October 21 commemorates the sacrifices of the 10 policemen while defending India's borders with China in 1959 at Hot Springs in Ladakh.
