Senior officials are considering a move to lower the age of criminal responsibility in Macau to crack down on the use of juveniles to carry out triad crimes. Chief Executive Edmund Ho Hau-wah said yesterday his administration was considering the possibility of lowering the age. He was reacting to questions on how the authorities would tackle a spate of arson attacks. Judicial Police have blamed gangs of teenagers for fire-bombings in which 39 motorcycles were destroyed on Thursday. No one was injured but dozens of residents were forced to leave their homes between 4am and 5am because of dense smoke. Police intelligence points to the likelihood that the arson attacks, in the Inner Harbour area, were committed by a gang of teenagers. Under Macau law, no one under 16 can be held criminally liable for offences. Offenders under 16 can only be sent to a reformatory for counselling. They cannot be sentenced as criminals nor can they be formally arrested or imprisoned. Several community leaders have proposed the age of criminal responsibility be lowered to 15 or 14. A source said the Government was proposing to reduce it to 14. The move would have to be approved by the legislature.
