New Delhi, Sep 23 - The Central Bureau of Investigation (CBI) Wednesday submitted before a city court that the witnesses, who deposed against the alleged role of Congress leader Jagdish Tytler in the 1984 anti-Sikh riots, were not reliable.

Additional CBI public prosecutor submitted before Additional Chief Metropolitan Magistrate Rakesh Pandit that the two witnesses, Surinder and Jasbir Singh, are unreliable as they have contradicted their statements on various occasions.

CBI counsel also said the statements of these two witnesses hold no credentials and were given only to falsely implicate Tytler.

Citing the case of Surinder, who deposed against Tytler and died recently, CBI counsel said: 'Surinder, in his first affidavit before the Nanavati Commission in January 2002, had stated that Tytler along with others had attacked Gurdwara Pul Bangash and killed Thakur Singh and Badal Singh. But in another affidavit in August 2002 he denied Tytler's role.'

The court, after hearing CBI counsel, slated the next hearing Oct 31, when the probe agency will argue on the version given by Jasbir Singh.
