Chief superintendent, Chris Kunyanban, said petty criminals are changing tactics, especially at the main bus stops.
Commuters in Lae have been warned to remain vigilant as petty criminals have now changed the way they conduct their activities due to constant police presence and CCTVs.
Kunyanban said petty thieves sometimes pose as PMV bus drivers or crew, where they stand near buses and call out the route. Commuters, believing their scam, would lower their guard. Once the bus drives off, the thugs would turn on the nearby commuters and rob them.
