Sahi was 55 and is survived by wife, a son and a daughter.
Condoling his death, Punjab Chief Minister Parkash Singh Badal said was as a fine human being, an upright politician and a disciplined solider of his party who always played a pivotal role in ensuring overall development of the state especially the Kandi area and the welfare of its people.
With his demise, the state has lost a balanced and experienced leader, who believed in clean and value-based politics.
Deputy Chief Minister Sukhbir Singh Badal said Sahi was a grassroot leader and had a very important place in Punjab's politics.
BJP leader and Punjab Local Bodies Minister Chuni Lal Bhagat also expressed deep grief on the demise of Sahi.
