Mohammad Yasin

Commissaries general Muhammad Jasin (also Moehammed Yasin; 9 June 1920 – 3 May 2012) was a National Hero of Indonesia and died on 3 May 2012 in RS Polri Kramat Jati, and he was buried in Taman Makam Pahlawan Kalibata. He is regarded as the founder of the Brimob Polri, which he formed from the existing Japanese-controlled Special Police Corps (Tokubetsu Keisatsutai).

In August 1945, Police Inspector Muhammad Yasin commanded a special police corps named "Pasukan Polisi Istimewa" (Special Police Troops) at Surabaya, with the task of disarming remnants of the Japanese Imperial Army and protecting the chief of state and the capital city. Yasin's special troops fought in the revolution and were the first Indonesian military police unit to engage in the Battle of Surabaya (1945).

Since 2024, 21 August has been declared Police's Struggle Day in Surabaya.
