A large number of protestors have gathered today outside the Rosalie Unit in Castlerea, as the first of the residents was due to be transferred to another facility this morning.
Last week, the HSE confirmed that the Rosalie unit will cease to function as a community psychiatric unit.
Following assessments of the 12 residents, the HSE said two required inpatient psychiatric care in a different setting, while transition plans are being put in place for all of the residents.
It was expected that the first of the 12 residents in the unit would be transferred elsewhere this morning, but it's now believed that has been deferred.
Large numbers of local people have gathered since early morning to protest at the closure of the unit.
