October 21, 2025 marks the 66th Police Commemoration Day observed annually across India to honour police personnel who laid down their lives in service. The date commemorates the tragic Hot Springs Ambush of October 21, 1959, in which Chinese PLA troops ambushed a patrol of the Central Reserve Police Force (CRPF) in Ladakh's Hot Springs area — killing 10 personnel and capturing several others. It was one of the earliest violent Chinese transgressions along the LAC. The Rajasthan Police also observed the day with state-level ceremonies. The event is significant in the context of India's ongoing border management challenges with China along the LAC and the continuing role of paramilitary forces in border security.
