Police in Auckland are planning to crack down on Chinese gangs who are using intimidation and violence to recruit high school students. Sergeant Simon Bennett, head of Auckland's Asian Crime Unit, said yesterday police were worried about increasing reports of recruiters beating up students who refused to pay 'initiation' fees of several thousand dollars to join two or three Chinese gangs that had established themselves in the city, New Zealand's largest. He said once a handful of students in each school had joined, one of them was appointed 'big brother' to carry on recruiting at the school. Sergeant Bennett said the students were being put under pressure to join the gangs or lose face among their peers. The main police concern was that the Chinese gangs were increasingly involved in crime in the city.
