In an application filed in the court, Harvinder's advocate said, "On November 24, 2001, when he was (Singh) was in convention centre, NDMC building, Palika Kendra, Connaught Place, New Delhi, he suddenly met with stroke/bout of mental disorder and lost his senses and is unaware what has happened after that."
Harvinder's neighbours had also claimed to be fed up with his behaviour and said that Singh rarely spoke to them, calling his behaviour psychotic. They also said that he had a history of violence.
Agriculture Minister Sharad Pawar had come for a function at Parliament Street when Singh attacked him like a bolt out of the blue. He slapped Pawar and shouted slogans calling him corrupt.
"During interrogation, he said he wanted to teach corrupt leaders a lesson by attacking them," said the police after he was taken to the Connaught Place police station where he was interrogated.
Now citing the sudden change in Singh's statement in court, many started speculating that politics have played a part.
In the application to the court, 27-year-old Harvinder also said, "The applicant (Singh) is in custody for last 20 days and is undergoing treatment in IHBAS and the applicant has serious apprehension of his life as the possibilities of political pressure cannot be overruled."
