Mamata Banerjee on Thursday directed agitating doctors in Bengal to resume work within four hours and threatened to take action if the order is not followed.

Mamata, who had yesterday deployed her nephew, MP Abhishek Banerjee, to make the first public statement from Trinamul on the strike, reached a state-run SSKM Hospital to take stock of the situation on the second day of the doctors' agitation.

The agitation started on Tuesday after two junior doctors of NRS Medical College and Hospital were assaulted allegedly by 200 men. The trigger of the attack was the death of a septuagenarian patient.

When Mamata visited the hospital, agitating junior doctors shouted: 'We want justice.'
