Punjabs take their livelihood seriously.
They will not and should not get sued. They were doing the right thing by detaining a shoplifter until the police came. The guy was resisting and struggling so that's why it looked worse than it actually was. Wasn't like they were hitting and punching him. They just wern't going to let him leave the store.
I applaud those punjabs for taking aggresive action. Shoplifting is shoplifting. Doesn't matter if it's over a candy bar or whatever.
