Sex offences by juveniles have been committed by increasingly youthful individuals in the past four years, with three offences perpetrated by 11-year-olds in the 12 months to March - the first period in which offenders have been so young, a study shows.
Half of the 30 teenage sex offences reported to police in the northeastern New Territories this year involved youths aged 11 to 14, the highest number in four years and three times the five cases that occurred in 2009, according to the research, carried out by the Evangelical Lutheran Church Social Service of Hong Kong (ELCHK).
Researchers, who examined data for the period April 2009 to March this year, said young people's use of social media could be the most important factor driving the trend. Their constant interactions on Facebook, WhatsApp and Weibo have made their relationships closer in a shorter period of time - possibly prompting them to act more intimately when meeting in person, said researchers.
The study covered all cases in Sha Tin, Tai Po, North District and Yuen Long under the Police Superintendent's Discretion Scheme, in which police superintendents issue cautions to offenders under 18 if they admit the offences and put them under supervision for two years or until they reach 18.
Offences listed under the scheme are deemed less serious, and include indecent assault, having sexual intercourse with girls under 16, stealing underwear, indecent exposure and upskirt photo-taking.
Almost 90 per cent of the 118 cases in the research period fell into the first two categories.
