A cellphone used to video a man being arrested at a Christchurch house where two police officers were shot is being sold on TradeMe.
The footage, which is still on the phone, was used by both television news networks and shows the man alleged to have shot the officers being arrested by the armed offenders squad.
It was filmed from the second story of a neighbouring house.
The owners of the cellphone say the proceeds from the sale will go to a charity to support police dogs.
Police dog Gage was killed during the siege.
The auction closes on Wednesday.
