The 33-year-old star wrestler took to social media to vent his anguish.
Questioning Khan's appointment Dutt wrote on Twitter "We have sportspersons like PT Usha and Milkha Singh who have strived hard for the country during difficult times. What has this ambassador (Salman Khan) done in sports."
Everybody has a right promote movies anywhere in India but Olympics is not a place for movie promotions. What is the role of goodwill ambassador, Can anyone tell me? Why are you fooling the public? he wrote.
Salman Khan was on Saturday named goodwill ambassador of the Indian contingent for the upcoming Olympic Games in Rio de Janeiro -- an unprecedented appointment in the run-up to the quadrennial extravaganza.
The announcement was made in the presence of Olympic medallists and Rio star athletes such as boxer M C Mary Kom , hockey captain Sardar Singh, and shooter Apurvi Chandela, among others.
The association between Salman Khan and the Indian Olympic Association was facilitated by IOA's official marketing agency IOS Sports & Entertainment.
