Those detained are a Provincial Court Clerk assigned to the Administrative Litigation Registry and an assistant clerk working in the Administration and Finance Department, in the assets management area.
The two officials are suspected of involvement in acts of corruption. Following their detention, they were taken to the GCCC for further legal proceedings.
According to information reported by the newspaper Domingo, the arrests are linked to allegations that money was being demanded in exchange for speeding up the processing of administrative cases.
Authorities have not yet officially disclosed the specific facts behind the allegations or the amounts or benefits potentially involved.
The two suspects are expected to appear before an investigating judge on Thursday, 17 September, for their first judicial hearing.
The case comes as authorities intensify calls for stronger measures against corruption within the justice system.
In June, Attorney-General Américo Letela warned that corruption in the justice sector poses a threat to the rule of law, calling for greater integrity, transparency and accountability among magistrates, investigators, officials and technical staff.
This week, during national meetings of the offices responsible for combating corruption, organised and transnational crime, and asset recovery, Letela again stressed that integrity should be a central principle guiding institutions within the justice system.
The two officials remain suspects and are presumed innocent unless and until found guilty by a final court ruling.
