The action movie star turned climate change campaigner allegedly failed to declare a custom-made watch by Audemars Piguet, which he intended to auction to raise funds for The Schwarzenegger Climate Initiative.

Officials at Munich Airport asked him to pay a €35,000 fine – but then struggled to find a working card machine or other suitable method for him to pay, CBS News reports.

Schwarzenegger was taken to an ATM, which could not dispense as much as €35,000, and to a bank which turned out to be closed. Staff were eventually able to locate a working card machine for him to pay.

He was allowed to continue his journey to Austria without the watch, which remains the focus of a criminal investigation into possible tax evasion.
