** Beltek Robbery **
Beltek in Gordon's in the National Capital District (NCD) recently had to call for help from the police when they were robbed but the police station they called only had Australian Police in attendance. Under an agreement the Australian police are not allowed to attend to any incident without the company of PNG police personnel. To top it off it is not just an ordinary PNG policeman that must attend with the Aussie police but also a specially trained policeman. The NCD / Central Province Commander is now expecting a report as to why there were no specially trained PNG police at work at the time of the call. Beltek lost two vehicles when criminals stole them from workers coming to work at 7:30 in the morning. Beltek have recovered one of the stolen vehicles and the other is still unaccounted for.
