MTR workers should be given the authority to stop and search suspicious people, according to Lau Kong-wah, chairman of the Legislative Council's transport panel. The MTRC said it was considering asking the government to give its staff such powers. 'MTR staff should be given such powers for the sake of public safety. The lack of such powers renders the bylaws on items banned on trains meaningless, as the rules cannot be enforced,' Mr Lau said. An MTR spokeswoman said an internal taskforce had been set up to review the company's response to Monday's arson attack. The taskforce would also consider the need to install closed-circuit television cameras inside train compartments and address passengers' complaints that they had difficulty opening the emergency windows during the arson attack. Under the MTR by-laws, it is an offence to bring inflammable and dangerous goods, including fireworks and paint remover, into trains or stations. The offence is punishable by a maximum fine of $5,000 and a six-month jail term. According to the MTR, there has only been one successful prosecution of a passenger for carrying dangerous items. The conviction in 1995 resulted in a $300 fine. MTR staff can currently only search passengers with their consent and can ask people they suspect of carrying dangerous items to leave. They can summon police to help deal with people who refuse to co-operate. But James To Kun-sun, chairman of Legco's security panel, said giving MTR staff the power to conduct searches would do little to prevent another arson attack. It was more important, he said, to increase education on emergency evacuation procedures.
