Khokhar was responding to the high court's March 29, 2017, decision ordering re-investigation and re-trial of five anti-Sikh riot cases against him and others.
A bench of Acting Chief Justice Gita Mittal and Justice Anu Malhotra had sought to know from them as to why it should not order re-investigation and re-trial against them as they had faced allegations of "horrifying crimes against humanity".
"Rather he helped the riot victims at later stage. He had been named by the complainant after a long period which is totally an afterthought. He had no role to play in the riots committed by unruly mob," the affidavit stated. Khokhar was produced before the court from the Tihar Jail here.
It said when a group of 200-500 people attacked a house, it is very hard to recognise a single person in the mob.
