The state government Monday served notices to the medicos and asked them to return to work or face action, an official said.

A day after Chief Minister Nitish Kumar expressed his anger at the doctors' strike that has paralysed health services in the PMCH, Health Secretary C.K. Mishra served notices on doctors asking them to report back on duty.

More than 400 junior doctors went on an indefinite strike, first demanding a hike in stipend and then payment of salary instead of stipend.

The strike has badly hit emergency, outdoor and surgery services of the hospital.
