Three staff and a film crew from ABC TV's program The Chaser's War on Everything have been questioned by police after being involved in second stunt in central Sydney this afternoon.

The three were released by police after being briefly questioned for carrying around black cardboard boxes dressed up as limousines in Sydney.

The Chaser's Craig Reucassel, speaking moments after being released by police, says the event happened well away from the APEC lockdown zone.

"The police basically just detained us and just checked whether we'd breached any laws - which we hadn't - and we're on our way," he said.

"We had boxes, but it'll all be on the Chaser, there was basically no problem."

Chaser member Chris Taylor says all involved knew no laws had been broken.

"We didn't do anything wrong at all, we were very careful to stay within the letter of the law, I think the police realised that so it was fine," he said.

On Thursday, eight other members of the Chaser program and three hire car drivers were charged using new APEC powers for allegedly entering a restricted zone in real cars with Canadian flags.
