Mobile internet is suspended across the state and more than 100 of Amritpal Singh's supporters have been detained.
But despite numerous roadblocks and a dramatic live-streamed car chase, they have not caught the self-styled preacher whose whereabouts are unclear.
His calls for a separate homeland for Sikhs have revived memories of a 1980s insurgency in which thousands died.
Amritpal Singh claims to draw inspiration from Jarnail Singh Bhindranwale, a preacher accused by the Indian government of leading an armed insurgency for a separate Sikh homeland - Khalistan - in the 1980s. Bhindranwale was killed in the Indian army's controversial Operation Blue Star in 1984.
