The documentary by CCTV was part of a series on Chinese police and high-tech crime-solving methods. A few seconds of footage showing Zuckerberg and Chan walking behind two police officers were shown included in a brief clip posted online by the Hebei province satellite station.
The footage shows the couple wearing the same clothes they were photographed in during a March 27 visit to Shanghai. Zuckerberg wears his custom hooded sweat shirt, this time in brown, and blue jeans, while Chan wears a printed short dress.
The clip shows Zuckerberg looking at the back of the police officers and smiling broadly as the couple walks off-screen. As they are shown, the narrator says: "There is a serious shortage in China's police manpower."
Zuckerberg has visited China to vacation and to meet with high-tech entrepreneurs, including a 2010 lunch with Robin Li, CEO of leading Chinese search engine Baidu. He married the 27-year-old Chan on May 20 in a private ceremony at their home, during the same week that he turned 28 and stock for the social network site began trading publicly.
A spokesman for Facebook, based in California, declined to comment Monday on the video clip.
Watch the clip below; Zuckerberg and Chan appear at the 30 second mark.
