Hong Kong police arrested another person on Wednesday suspected of being involved in the Monday night Mongkok riot in Fanling, bringing to 64 the number of people jailed on suspicion of participating in the riot.

Ko Wing-man, secretary for Food and Health of the Hong Kong Special administrative region, said more than 130 people injured in the incident were hospitalized, among whom more than 90 are police personnel. He said 13 people were still receiving hospital treatment as of Wednesday night and were in stable condition.

John Tsang Chun-wah, financial secretary of Hong Kong, said: "What happened in Mongkok on the second day of the new year on the Chinese lunar calendar makes me very sad and very outraged. Such irrational actions have gone far beyond our rule-of-law base line and are unacceptable to society.
