Jasbir Singh, a key witness in the anti-Sikh riots case against Congress leader Jagdish Tytler, on Friday said that the Central Bureau of Investigation should approach him in the United States to record his statement as he feared for his life in India.

"I will give 100 per cent cooperation to them (CBI) if they approach me here (California). Why won't I cooperate? For 23 years, I am waiting for justice," Singh told NDTV.

Singh claimed that he decided to settle outside India as the witnesses in the anti-Sikh cases were facing threats.

"My life is under threat. I am staying here to save myself," he said.

Singh said that the CBI knew his whereabouts and wondered why its sleuths were not approaching him. "They should record my statement and then the court will decide the matter."

CBI had filed a closure report in the 1984 riots case involving Tytler and had claimed that Jasbir, who had submitted an affidavit before the Nanavati Commission, was not traceable.

However, he suddenly surfaced on various TV channels claiming that the CBI had never approached him.

Sattu Singh, father of Jasbir, claimed that his son was being threatened in the United States.
