AT night a group of vandals frequent the sixth to 10th floors of Fung Chak House, at Choi Wan Estate, Kowloon. Over a period of several nights, they have vandalised the corridors on these floors by spraying red paint on the walls. Some residents have not been allowed to pass while the vandals do their work, and others have been threatened. We have complained, because we fear that there may be a triad influence at work here, but so far, nothing has been done. We would appreciate if the police would look into this as a matter of urgency and ensure that these vandals are removed from the estate. We are naturally concerned about the safety of all residents.
