A growing number of people in Hong Kong who have taken part in the city’s recent pro-democracy protests are suddenly finding themselves denied entry into China.

The action has shocked many and sparked widespread belief that Chinese authorities have assembled a blacklist with hundreds, perhaps thousands, of names in recent months.

Many recently denied entry attended that same summer protest, which drew one of the biggest pro-democracy crowds in recent years. More than 500 were arrested and released with warnings.
