They stopped the bus around 1.15am and checked all the passengers. Police scrutinized their ID cards, ordered passengers to remove their masks, and at 1.45am were still searching people. Passengers were made to stand on one side of the bus while the police searched others.

Officers move to disperse crowds after breakaway group stormed parliament building

Hong Kong police have fired teargas at demonstrators and moved to disperse crowds after protesters stormed the legislative council building and raised the territory’s former colonial flag on the 22nd anniversary of its handover to China.

The dramatic scenes came after a peaceful march of half a million people made its way through other parts of the city as its deepest political crisis in two decades showed no sign of abating. For the past month protesters have been demanding the withdrawal of a bill that would allow extraditions to the Chinese mainland as anger has grown against Hong Kong authorities and the territory’s chief executive, Carrie Lam.

Hundreds of protesters have stormed the Hong Kong government building on the anniversary of the city's 1997 return to China, destroying pictures and painting walls with graffiti. More than 1 million people have taken to the streets in protest against planned legislation that would permit extraditions to China
