The latest is a report of policemen cutting and wounding a number of persons with bush knives in Port Moresby.
The incident happened following an ethnic clash at the 8 Mile settlement over the weekend.
A relative of the victims told NBC News, his relatives were forced to lie on the ground after they were stripped off their personal properties while policemen cut their archilles tendons with the knives they were carrying.
Commissioner Kulunga demands that the incident be confirmed, and that the responsible officers be charged and locked up before 12 noon today.
Mr Kulunga says his warning stands that there is no place for animalistic behaviour within the Constabulary adding that he needs public help to weed out corrupt and abusive officers.
The recently launched Police Modernisation Program is also designed for police to change their mindset and attitude into one of respect and service to the people.
The incident involved a group of men from Morobe.
A relative told NBC News, they were returning from a mediation over an incident on Sunday when they were stopped by a police vehicle and attacked with knives.

An ethnic clash broke out between the Morobes and Sepiks, leaving houses burnt and properties destroyed, following the stabbing death of a man from Morobe on Saturday by four drunks of East Sepik origin.
Police have since been patrolling the area, to prevent further sporadic clashes.
