Babbu Chandigarhia alias Shubash, a local Punjabi singer, had went to attend a marriage party at the lawns of Punjab Cricket Association stadium at Mohali last night.
At the function some youths asked the singer to sing at the function, police said.
However, he refused to oblige saying he was at the function as a guest and not as a singer.
This infuriated the youths allegedly owing allegiance to Akalis who thrashed him.
Police said that guilty would not be spared at any cost.
Meanwhile, sources said the party was organised in connection with the marriage of a distant relative of an Akali leader Balwant Singh Ramoowalia.
