Later, the police along with a district magistrate broke open the lock of the office chamber.
The KSU is protesting against the ongoing standoff between the cardiology department and the NEIGRIHMS administration.
The KSU also demanded that NEIGRIHMS director DM Thapa should be “removed immediately”.
Hundreds of KSU members led by its president Lambokstarwell Marngar and general secretary Donald V Thabah went to the hospital and shut down the office of the director holding him responsible for the ongoing imbroglio in NEIGRIHMS.
The KSU also held the director responsible for the death of a patient allegedly due to non-availability of equipment in the cardiology department to treat her.
The KSU said that it would continue to protest if the government failed to pay heed to its demand to remove the present director.
The Meghalaya government was also slammed for its failure to put an end to the imbroglio to ensure that patients did not suffer.
The KSU said that it would also write to the union health minister on the issue.
NEIGRIHMS has been in the news since last week. A standoff between doctors of the cardiology department and the administration led to the shutting down of operations in the cardiology department.
NEIGRIHMS authorities clarified that the services in the cardiology department were shut down because the head of cardiology department has not been “co-operating with the administration with regards to making treatment of poor patients affordable as per the union ministry of health and family welfare regulations”.
