However, Kejriwal, currently on a three-day campaign trail to various parts of Haryana and Punjab, disapproved AAP supporters thrashing of the attacker, identified as Jitender Leghan of Leghan village. He was later arrested and questioned by local police.
"Someone hit me hard on my neck jst (just) now. This kind of violent reaction is expected of them. It only shows their true character and desperation," the AAP leader tweeted after the incident without elaborating who he was referring to. The attacker also tried to slap him.
"Our supporters beat him up in retaliation. That is very wrong. That is not expected of us.
"I am deeply hurt by the reaction of our supporters. If we also react violently, then what is the difference betn (between) them and us?," he said.
