The Terminator actor and his bodyguard broke the rules at Munich's main station on Friday (30Sep16) and were stopped by a German federal police officer.

According to Germany's Der Spiegel newspaper, the policeman did not take any further action after the 69-year-old star apologised and explained that he was having difficulty walking.

The Austrian-born star also agreed to take a photo with the officer before being allowed to go on his way.

"After brief small talk with the federal police officer, the Terminator left the main station through the north entrance," a spokesperson for the German Federal Police said in a statement, adding that Arnold had walked away pushing his bike.
