Cheong Wa Dae has belatedly revealed that it dismantled a security gate in front of the office of the presidential secretary for civil affairs guarding sensitive documents during the Park Geun-hye administration.
In a Facebook on Monday, Cheong Wa Dae said a "suspicious checkpoint" equipped with hi-tech sensors guarded one of the two stairways leading up to the third floor, while the other was blocked with screens and steel bars.
According to Cheong Wa Dae, the bottleneck was set up at the orders of the presidential secretary, Woo Byung-woo, to prevent sensitive documents from being taken out of the presidential office.
Woo is on trial for his role in the cover-up of the corruption scandal that brought Park down. The office for civil affairs apparently used only treated paper that set off alarms when taken through the gate or when photographed or photocopied.
Cheong Wa Dae staffers who worked there during the Park administration corroborated the findings.
Cheong Wa Dae said it dismantled the gate on June 29 because they were a symbol of the "authoritarian and non-communicative" nature of the former government.
Park was notoriously cagey and hated any kind of public oversight, as it transpired for good reason. The new government has made greater transparency one of its top objectives.
