Long time overdue. Sweeps should have been carried long time ago regularly at Geylang, Little India, Tg Katong, Joo Chiat, Orchard Rd for criminal elements from China, Vietnam, etc. Where vice activities occur, criminal elements will flourish. When SPF is complacent; we see nothing, we do nothing, security in SG is just a joke. Sweep all these areas regularly and prevent foreign criminal gangs from operating freely in SG. Learn the lessons from USA. Foreign criminal gangs are now a part of American way of life. Is our SPF a fighting force or .... ?
