The Star has this story headed "Cops seal Selangor state secretariat" and the article mentions
"We took charge of the building, as it belongs to or is under the jurisdiction of the state secretary, who is also the caretaker of the state.
“No one other than him or his deputy or appointed officials, is allowed to enter,” he said when asked about officials from the previous administration trying to force their way into the building."
I suggest that to avoid possible complications, absolutely no one should be allowed access into the building unless accompanied by a third party, like a person authorised by the incoming administration.
My suspicious nature urges me to suggest that the government has been in power for so long it is possible for unhealthy links to have been developed with supposedly neutral persons.
