Student leaders of pro-democracy protests in 2014 were found guilty of illegal assembly by a Hong Kong court, local media reported Thursday.
Joshua Wong and Alex Chow were convicted for climbing into a fenced-off area in front of the government headquarters in September 2014, Radio Television Hong Kong said.
Student Nathan Law was found guilty of inciting people to join the protest.
The students could face up to five years imprisonment.
"I don't regret my committment to the Umbrella Movement," Wong told dpa.
"This conviction will be more pressure, but it doesn't mean I'll step [back] from my responsibility [of fighting for democracy]"
Wong and Law are now part of a newly formed political party, Demosisto, which is planning to field candidates in September's legislative council elections.
