Joshua Wong scores legal win related to 2014 Hong Kong protests

A Hong Kong court on Tuesday acquitted teen pro-democracy leader Joshua Wong of obstructing police at a protest two years ago against China's tightening hold on the city.

Wong tweeted that he and three others were found not guilty. It's the first verdict in a number of court trials Wong is facing.

The 19-year-old activist captured world headlines when he led pro-democracy street protests in late 2014 against Beijing's decision to restrict elections in Hong Kong, a semiautonomous Chinese region.

The obstruction charges, which carried a maximum two-year sentence, stemmed from a separate protest months earlier in which Wong and the others set fire to an oversized cardboard prop representing a "white paper" policy document issued by China's communist leaders.

"The result of this trial is already proof that it's just a political prosecution," Wong tweeted after the verdict.

The document angered many in Hong Kong because it asserted Beijing has "comprehensive" authority over Hong Kong. It also said that many Hong Kongers had a "lopsided" view of the "one country, two systems" principle that outlines the former British colony's relationship with Beijing.

The so-called Umbrella Movement was the most serious unrest in the city China took it back from Britain in 1997. Many activists carried yellow umbrellas, a symbol of the fight after protesters used them to try to fend off tear gas attacks.

Prosecutors said police officers moved in to try to douse the flames with bottles of water but were blocked by Wong and another student protest leader, Nathan Law, according to local media reports. However, the defence team argued that they were pushed from behind by the crowd and couldn't hear police, the reports said.

Two other activists who appeared alongside Law and Wong were also cleared. The charges could have led to up to two years in jail.

Wong is also accused in a separate trial of inciting student demonstrators to storm a courtyard at Hong Kong government headquarters in September 2014, leading to a standoff between thousands of supporters and police, who responded with tear gas. The verdict in that case is expected at the end of the month.

He also faces trial on contempt charges for allegedly blocking police trying to clear a protest zone in Hong Kong's Mong Kok district in November 2014.
