Hong Kong police arrest man who played harmonica at Queen's vigil on suspicion of sedition

A man was arrested in Hong Kong on suspicion of sedition after playing the harmonica at a vigil for Queen Elizabeth II, under a colonial-era law that once outlawed insulting the Queen -- and has now been revived by authorities amid an ongoing crackdown.

Videos posted to social media show hundreds of people gathering outside the city's British consulate on Monday night to pay tribute to the Queen, as her funeral took place in London -- an event heavy with political significance in the former British colony, where mourning the monarch has become a subtle form of protest.
