Acting on the information, Shahid and Rashid were arrested.
Delhi Police sources earlier said Shahid and Rashid with another LeT member went to collect scriptures from Muzaffarnagar to radicalise the riot victims to join the outfit.
Counsel Khan said there were several loopholes in the story projected by police, but those cannot be disclosed as it would destroy the defence of the accused.
Citing a matter against suspected Hizbul militant Liyakat Ali, Khan requested the home ministry to direct the NIA to investigate his clients' case in a fair and impartial manner, saying that the matter has national ramifications.
Liyakat Ali was arrested by Delhi Police for allegedly conspiring to carry out terror attacks in the capital in March 2013. He was later granted bail by a special NIA court in May 2013.
In March 2013, the home ministry had issued a notification facilitating the NIA to take over the case after Ali's arrest generated conflicting versions from Delhi and Jammu and Kashmir Police.
