The move came after a special CBI court in July had given the agency last chance to complete its probe in two months in the case against Tytler.
Tytler today appeared before the investigation team where he answered to the questions put by the investigating officers, sources said.
Additional Chief Metropolitan Magistrate Shivali Sharma, while directing CBI to complete the probe, had made it clear that if there were no fruitful results in these two months, the agency's Superintendent of Police would have to explain.
The court had on December 4, 2015, directed CBI to further probe the riots case against Tytler, saying the statement of arms dealer Abhishek Verma had revealed an active role played by the Congress leader in extending "helping hand" to a witness against him.
