Specifically asked whether Roy, once chief minister Mamata Banerjee's powerful aide, would be served show-cause notice for his comments, the TMC leader told PTI "he is going too far".
The leader referred to Roy picking up one issue after other to embarass the party and Mamata Banerjee government.
"The party is dealing with it seriously. He is making comments and has met Prime Minister Narendra Modi and a Muslim religious leader Peerzada Toha Siddique known to be a staunch critic of Mamata Banerjee government accusing it of 'failure' to fulfil the promises about the minorities."
The report is likley to be used for further action against Roy who has fallen out of favour with Mamata over the Saradha scam.

Earlier today in a strong message to Roy, party secretary-general Partha Chatterjee said it was keeping a close watch on him as he was picking up issues one after another to embarrass the party and the government.
Chatterjee was replying when his attention was drawn to Roy's controversial comments concerning the affairs of the party and the government.
"If a party worker declares war sitting at home, that will not cause damage to the party. People are themselves are privy to the entire episode... They will take a call on this," Chatterjee said on the sidelines of a programme at Suri, headquarters of Birbhum district.
Chatterje's observation came a day after Roy had launched a fresh tirade taking a dig at the industrialisation claims by the state government.
