Four Gisborne men facing serious charges following a Trade Me vehicle swap were remanded on bail on Friday.
The men, two aged 20, one 17 and the other 22, are charged with aggravated robbery, kidnapping and unlawful possession of a firearm.
The charges follow an incident in Rotorua on Thursday in which it is alleged the four demanded at gunpoint the return of a vehicle they had swapped with a local man through the website earlier in the week.
Police allege that when the men got back to Gisborne, they became unhappy with the quality of the vehicle.
They were remanded on bail, subject to strict conditions, to appear in Gisborne District Court tomorrow.
