The governor had earlier termed as "ghastly and alarming" the attack on the ED team and CRPF personnel accompanying them during the raid on the house of TMC leader Sheikh Shahjahan in connection with the alleged ration distribution scam. Shahjahan has been missing since then. "It is the duty of a civilised government to stop vandalism in a democracy. As governor of the state, I am exploring all Constitutional options to take appropriate action," Bose had said after the incident.
