*EDITORS PLEASE NOTE: EDIT CONTAINS GRAPHIC IMAGES* Hong Kong's political crisis has taken a violent new turn.
This graphic footage came from a reporter who live streamed the attack at a rural train station Sunday (July 21) night.
After weeks of clashes between demonstrators and police, the spotlight has shifted to the territory's shadowy criminal network.
Some opposition lawmakers say the men in white were triad gangsters.
They were seen attacking passengers, one Democratic lawmaker said they appeared to target people wearing black shirts coming back from the day's anti-government protest.
The scene quickly descended into chaos.
Authorities say 45 people were injured in the attacks with one in critical condition.
One lawmaker said it took police more than an hour to show up after he called them.
One man was seen begging on the metro.
And later beaten up by men in white.
On Monday (July 22), police defended their actions and the lack of arrests.
Hong Kong's police chief said the force had waited for reinforcements.
Rolling protests are still taking place across Hong Kong.
What started as a movement against the now-suspended extradition bill - is morphing into a list of demands, with some calling for full democracy in the Chinese-ruled city.
(SOUNDBITE) (English) MASKED PROTESTER SPEAKING OUTSIDE THE LIAISON OFFICE, SAYING: "We urge the government to stop leading Hong Kong towards the brink of destruction, and work together with the people to bring our city back to a path of a united, democratic and free, just, society." Police say they made the largest seizure of its kind in the city when explosives and weapons were found in an industrial building on Friday.
It's still unclear if they were related to the weekend's protests.
On Sunday thousands had descended on China's representative office in the city throwing eggs and spray painting graffiti on its walls.
They were finally driven away by police using tear gas and rubber bullets.
Leader Carrie Lam said it was a challenge to national sovereignty.
But demonstrators have said they won't stop until their demands are met.
