Thieves have ransacked an office belonging to Papua New Guinea's anti-corruption taskforce, stealing laptop computers and files.About 20 men are believed to have tied up three security guards and broken through a heavy steel gate to get to Taskforce Sweep's administration office.
The office was left trashed with paper strewn everywhere and drawers emptied onto the floor.
Taskforce Sweep's chairman Sam Koim says staff are still trying to establish what has been stolen.
He says some laptops and investigation files are gone but the break-in will not deter his officers.
"This is not going to discourage us. No-one will intimidate us," he said.
Taskforce Sweep's investigations have led to the arrests of dozens of politicians, bureaucrats and businessmen over the past 18 months.
