"The NSA is being invoked against them. We will not let leave them," he said, accord in a government statement in Lucknow.
The NSA allows preventive detention up to 12 months without a charge if the authorities are satisfied that the person is a threat to the national security or law and order.
The Ghaziabad police said the Jamaat members were booked for indulging in ugly acts and passing lewd remarks against the women staff members at the hospital.
A case was registered against them at the GT Road Kotwali on receiving a complaint from the chief medical officer.

In the complaint, a nurse has alleged that the coronavirus suspects were roaming without trousers in the hospital.
