"Whatever one has done, one has to bear the consequences. Who has arrested whom, how can I comment on that?" said Trinamool secretary general and state Education Minister Partha Chatterjee.
He said he kept away from such practices.
"I don't get involved in such things," Chatterjee said.
State BJP president Dilip Ghosh said the truth should come out and cases of corruption like Saradha ponzi scam and Narada should be taken to their logical climax.
"Mirza was heard saying in the tape that he had to collect money for the party. We want the truth to come out. The cases of corruption like Saradha ponzi scam and the Narada sting footage which have come into public domain, should be carried to their logical climax.
"The process should have started much earlier. Then people's trust on the CBI would have increased. Better late than never. Corruption should stop," said Ghosh.
Another BJP leader and Union minister Babul Supriyo said it was a significant development. "Those who have committed illegal acts, will have to suffer".
Congress Rajya Sabha member Pradip Bhattacharya said Mirza's arrest was expected.
"This was expected. The way he took money was repeatedly flashed in the media. The CBI hasn't done anything wrong by arresting him," said Bhattachaya, a former state Congress president.
Wondering why the CBI took three-and-a-half years to take Mirza into custody, Left Front legislature party leader Sujon Chakraborty said it was only the beginning and that more such arrests would follow.
"This is a very unfortunate scenario. We are having to bow our head in shame before the entire nation. An IPS officer says he has to collect funds for a party. Why did it take three-and-a-half years? Everybody has seen what all transpired in public.
"This is only the beginning. More such things will happen," the CPI-M state secretariat member said.
