The United Nations Development Programme says a texting scheme to expose corrupt government officials in Papua New Guinea has had a dramatic impact.
The agency says since the 'Phones Against Corruption' initiative was brought in last year two officials have been arrested on fund mismanagement charges.
Another five more are waiting on court decisions, and more than 250 other cases are being investigated.
Under the scheme workers in the Department of Finance are encouraged to send anonymous text messages detailing any concerns they have about the practices of colleagues.
Those messages go to the Department's Audit and Compliance Division for further investigation.
In a media statement the UNDP says since the scheme started last July 1,500 users have sent texts, which have been coming in at the rate of 38 a day.
