More than 20 Hong Kong democracy campaigners, including nine legislators, were barred from entering Macau ahead of a march against a proposed national security law, according to one of the lawmakers.
The group was stopped by immigration officials and detained for half an hour, before being put on a ferry back to Hong Kong, Emily Lau, deputy chairwoman of the Democratic Party, told AFP.
“They told us we have broken Macau security law, but they could not be more specific,” Lau said.
Among those prevented from entering was well-known activist and legislator “Long Hair” Leung Kwok-hung, chairman of the Democratic Party Albert Ho and former chief executive candidate Alan Leong.
