A mob in white T-shirts attacked commuters on a train at a Hong Kong station on Sunday (July 21).
Video filmed from a commuter hanging out of the train at Yuen Long Station shows the white shirts on the platform and lashing out at those inside through the open glass barrier.
At least 45 people were injured when masked thugs attacked protesters, according to reports.
More than 100,000 demonstrators marched through Hong Kong demanding greater democracy.
