Grillot suffered bullet wounds and is in hospital during the shooting in a Kansas bar last week.

"India salutes the heroism of Ian Grillot! Best wishes for a speedy recovery," Sushma Swaraj tweeted on Monday night.

Srinivas Kuchibhotla, 32, was killed and his colleague Alok Madasani was injured when Adam W. Purinton, formerly of the US Navy, shot them at the Austins Bar & Grill in Olathe, Kansas state, on February 22.

Purinton reportedly got into an argument with the two and hurled racial slurs. He yelled "get out of my country" before shooting them. 

Grillot, 24, who tried to save the Indians, was hit by a bullet that pierced his hand and then lodged in his chest.
