The men were taken in after they bashed up a neighbour at their Six-Mile residence.
The victim, another man from Wabag, allegedly borrowed K1000 from the duo last November and went into hiding somewhere in the city.
The duo caught up with the victim this morning at the Six-Mile market, where he was sitting with buai sellers.
He sustained a fractured jawline, a black eye and two bruised ribs from the confrontation. He is at the Port Moresby General Hospital.
The two men will be charged with assault and threatening words.
