BERLIN — A police officer in Germany got himself an unusual souvenir after finding none other than Arnold Schwarzenegger breaking the rules at Munich’s main train station.

Federal police say the officer stopped Schwarzenegger’s bodyguard, and then the movie star and former California governor himself, riding bikes Friday along the station’s platforms.

Police said Saturday that Schwarzenegger apologized, 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.”

It said Schwarzenegger walked away, pushing his bike. Ever conscious of health issues, Schwarzenegger urged fans to follow his lead on getting a little exercise.

“Never tell me you don’t have time to exercise,” the still-chiseled former bodybuilder captioned an Instagram pic. “Every time I visit a city, I go on a bike ride immediately. And I get to be your tour guide on Snapchat.”

According to the Daily Mail, Schwarzenegger and his girlfriend, Heather Milligan, were in Munich for Oktoberfest and sampled a brew at the Schuetzen Festzelt last Tuesday.

The Mail also reported that Schwarzenegger, who was born in Austria, donned a pair of traditional lederhosen to celebrate.

The Mail reported that the couple has been an item for around four years after Schwarzenegger’s 25-year marriage to Maria Shriver ended.
