They were foiled when bystanders decided to intervene and save the would-be victim.
One attacker aged 15 and the two others aged 17 were trying to force a driver out of his CRV car when the crowd turned on them and stepped in to chase them away.
Ironically the three were picked up by a nearby police unit who were on route to the Boroko police station for a change of shift.
The three were chased by some members of the public who attracted the attention of the police who stepped in to chase and apprehend the youths near the old Pacific International Hospital site.
The victim, a 43 year old Oro man, has lodged the matter with police while the three youths are being detained at the Boroko cells, waiting for formal charges to be laid.
