Shortly after a Delhi Court directed the CBI to re-investigate a 1984 anti-Sikh riot case involving him, former union minister and Congress leader Jagdish Tytler on Tuesday expressed doubts over the veracity of the affidavit of a witness, who has expressed his desire to assist the investigating agency.

The court took note of the reports that witness Jasbir Singh, who was declared untraceable by the CBI, spoke to TV channels from the United States that he was willing to record his statement with the agency.

Questioning the affidavit of Singh, Tytler said there were contradictions in it and he would be happy if he comes and make things clear so that entire conspiracy surrounding it will be exposed.

"If in his affidavit he has said that on the third (November 3, 1984), remember third is a very important date, when the whole of Delhi was under curfew with orders to shoot, even a stray dog can't be on the street that day."

At 11:30 in the night, he sees Tytler in a mob. In a curfew, can you imagine.... in a curfew on the third," Tytler told reporters.

"I want that man to come, because then the whole thing will be clear and then you will come to know what conspiracy it is and what lie it was," Tytler said.
