A 14-year-old boy has been arrested for claiming to be a member of a triad on his internet blog, in what might be the first case ever in Hong Kong. The boy was arrested at his home in Nai Wai, Tuen Mun, early yesterday, a police spokesman said. 'Police investigation revealed that the boy set up a blog in December 2006 and identified himself as a member of a triad gang active in Shan King Estate, Tuen Mun,' the spokesman said. In the blog, the teenager recorded a number of events, including his arrest for unlawful assembly earlier this month and his involvement in a fight against a rival triad. 'The blog was removed immediately after the arrest,' police said. The boy's blog was www.xanga.com/kaho426 - 426 is gang code for a senior level of triad leadership. Officers of the District Anti-triad Squad in Tuen Mun traced the whereabouts of the boy with assistance from the Commercial Crime Bureau's Technology Crime Division. 'The boy is now on HK$500 police bail pending further investigation,' the spokesman said, adding he had to report to the police next week. 'Police reminded the public that all existing legislation that prohibits criminality in the 'physical' world will equally apply to criminal acts committed in the 'cyber' environment,' he stressed. The arrest was rare as a senior police officer admitted last October that police no longer arrested gangsters simply for claiming to be members of triads because the offence was hard to prove in court. Criminologist Dennis Wong Sing-wing said while it was not uncommon for teenagers, and even children as young as 10, to claim they were triad members, he was surprised by the boy's arrest. 'It is very likely to be the first of its kind,' said the City University associate professor of social science, who specialises in the study of triads and crime by teenagers. 'Few triad members are active in the cyber environment. And no one will write down in black and white that he is with the triad,' Professor Wong said. He said that arrests for such an offence were often attached to other criminal activities, like intimidation or assault. The arrest served as a reminder to members of the public that the minimum age of criminal responsibility in the city was 10, the professor added. 'The age was seven originally but it was raised to 10 in 2003. Nevertheless, we really need to tell teenagers that they should take responsibility for what they do.' Anyone who is, or claims to be, a member of a triad faces a fine of HK$100,000 and three years prison for a first offence, and a fine of HK$250,000 and seven years prison thereafter. In 2005, there were 794 unlawful society offences, compared with 919 in 2001 and 824 in 2002, making up about 3 per cent of overall crime.
