Late Saturday, residents of Monrovia's West Point slum attacked a quarantine centre, where people were being monitored for possible infection with Ebola. Up to 30 of these suspected Ebola patients fled during the raid, when items including bloody sheets and mattresses were stolen.
Assistant Health Minister Tolbert Nyenswah said that at least some of the suspected patients were again being monitored at a hospital on Monday. It was not clear how they had been identified.
Liberian authorities have struggled to contain the current Ebola outbreak in West Africa and there are concerns that the raid will fuel the infection's spread.
