Police yesterday raided an elite kindergarten in Kowloon Tong which has been accused of overcrowding classes and overcharging parents. The surprise swoop came during school hours as part of an investigation into complaints against the York English and Chinese Kindergarten. 'We are checking the school records to see if it has admitted more students and charged more fees than it is allowed,' an officer from the Kowloon City District police station said. 'We raided the school after the Education Department sought help from us. The investigation is still ongoing. It's uncertain when we will have a conclusion,' he said. The officer said police tried to keep the investigation low-key because they did not want to disrupt lessons. 'We don't want to scare the pupils and the parents. But we are very concerned about the issue. 'We are determined to help the Education Department find out the truth,' he said. Police took some documents from the school in York Road. No one from the school was available for comment. The school has been warned by the Education Department for admitting 300 students more than allowed. Since it did not have enough classrooms to accommodate the excess students, they were forced to 'float' among classrooms, or learn in rooms not checked for safety. The school was also accused of charging $1,800 per pupil, when the department allowed it to charge only $1,510. Temporary measures are being worked out to reduce the number of students, including renting extra classrooms from a nearby kindergarten. Lee Yeung Wai-chun, senior education officer (Kowloon City District), said the department had sought help from police. She appealed to parents not to panic. Legislators will demand education officers explain why so many kindergartens are unregistered and over-enrolled at a panel meeting on Friday. The department said it had issued 59 warnings to schools, including the Gloria English Kindergarten in Kowloon Tong, for over-enrolment this year.
