A police officer in Germany picked up an unusual souvenir after finding movie star Arnold Schwarzenegger breaking the rules at Munich’s main train station.

The officer stopped Arnie’s bodyguard and then the Terminator star and former California governor himself from riding bikes along the station’s platforms on Friday.

Police said Arnold apologised, explaining he was having trouble walking, and offered to take a picture with the officer.

A police statement noted that “after brief small talk with the federal police officer, the ‘Terminator’ left the main station through the north entrance”.

Arnold walked away, pushing his bike, police added.
