Scholarism convenor, Joshua Wong, has warned that Hong Kong may witness more incidents like the Mong Kok riots if the approach of the CY Leung administration does not change.
Wong said various political parties and large sections of society have condemned the violence, but the government should accept responsibility for the social divide that exists.
He said some activists had become radicalised after the 2014 Umbrella democracy movement, because they discovered that peaceful movements like that cannot achieve any change. If government officials do not show more concern, he warned, things will get worse.
Talking to RTHK’s Ian pooler, Wong also said that while people indulging in violence were arrested quickly, such speedy action was missing against the police officers charged with beating up activist Ken Tsang during the Occupy protests.
He also described as "unreasonable" the arrest of one of the student group's members, Derek Lam. The 22-year-old was detained at the airport on Wednesday as he was about to fly out for a family holiday in Taiwan.
