Protesters removed barbed wire surrounding Government House and cut electricity and water supplies.
Firefighters inside Government House were escorted by protesters as they left the compound.
Protest leaders said they were informed by the deputy metropolitan police commander that police on duty in the Government House wanted to leave.
Meanwhile, the Interior Ministry has been held by protesters for the last 12 days and civil servants were barred from entering the premises.
Protesters put up a placard which reads “Ministry Serving People” over the original Interior Ministry sign, saying the ministry should look after the people’s well-being.
