NCD metropolitan superintendent, Commander Ben Turi, says two key suspects were apprehended after the robbery on Nov 3 and later released.
Unfortunately, one of them was found dead with two bullet wounds to his head last Monday.
Turi told Loop PNG the recovered bullet shell matches those that are used in police and military issued firearms.
“The bullet is from 5.56mm rifles used by police and army,” he explains.
However, he was not able to confirm whether the suspect was killed by rogue officers or criminals.
