The former Supreme Court judge also said that former joint commissioner of police Damayanti Sen be restored to her earlier office, from which she was removed after she cracked a rape case on Park Street.
"We all make mistakes but a gentleman is one who realises his mistake and apologizes.
"I request you to act against the policemen who ordered and implemented the arrest of Mahapatra and Chowdhury, you should immediately withdraw the cases against them and apologize to them."
He accused Banerjee of victimizing Damyanti Sen, who he said was an upright police officer. "You should apologize to her. You should also apologize to Tanya Bharadwaj whom you insulted on CNN-IBN show."
Bharadwaj, a young student, received the ire of the chief minister for questioning her on a TV show.
Katju said Banerjee's ministers and bureaucrats "are afraid to speak out their minds fearlessly before you, and are terrorised by your unpredictable and whimsical behaviour".
Stating that her ways were "very unhealthy", he said Banerjee "will not be able to remain chief minister for long unless she changed her ways and became more tolerant...
"It is still not too late if you listen to my advice and change your ways. I had praised you at one time. But of late you seem to have become increasingly intolerant and whimsical."
