The state finance minister, Amit Mitra, was badly heckled by the Left students' body who were protesting the state government's alleged insensitivity towards the death of one of its leaders in police custody in Kolkata on April 2.
The Trinamool Congress (TMC) had warned earlier that it would not allow the Parliament to function if no arrests had been made in the case. Banerjee was admitted to a hospital in Kolkata for some days in Kolkata while Mitra was treated at the AIIMS here. The Lok Sabha had to be adjourned minutes after resumption of the Parliament's Budget Session following the TMC's uproar over the issue.
The SFI initially tried to wash its hands off the incident by trying to put the blame on some other students' organisation but later had to apologise, reportedly under pressure from the Left Front camp in West Bengal, who believed that such a move had damaged its chances of making a comeback in the state further.
The Left had also drawn ire after the CM and her team was targetted in the national capital. A massive retaliation was launched by the ruling party across the state in which offices of the opposition and vehicles in which their leaders were travelling were ransacked.
The historic Presidency University in Kolkata was also vandalised with its students and teachers being beaten up in the wake of the Delhi incident.
