There was another Saturday afternoon acid attack yesterday - but the bottle hit an open concrete area at a New Territories housing estate rather than a busy pedestrian shopping area in Mong Kok. A 28-year-old man surnamed Leung was taken to hospital with burns on his legs when the bottle of acid, believed to be drain solvent, smashed into the ground near Yin Fu House, Tin Fu Court, in Tin Shui Wai, at about 9.40am. Security guards called the police and the man was taken to Tuen Mun Hospital for treatment. 'I was walking and listening to music when I suddenly felt pain,' Mr Leung said. Thirty people were injured in an acid attack in Mong Kok's pedestrian area on May 16, and 46 people were injured in the same area in a similar attack in December. Police have offered a HK$300,000 reward for information leading to the arrest of those responsible for the Mong Kok attacks. Victims of the May 16 incident were invited back to the scene yesterday for a reconstruction of the attack. William Tam, chairman of the Incorporated Owners of Tin Fu Court, did not believe the case was related to the Mong Kok acid attack. 'The area where the attack happened has a very low flow of pedestrians and there is quite a lot of construction work being carried out in Tin Fu House, as the flats were resold in previous months,' Mr Tam said. The case has been listed as an object dropped from height and is being investigated by Tin Shui Wai police. The owners' corporation will hold a special meeting tomorrow to discuss measures to prevent similar cases, included the possibility of installing surveillance cameras. Yuen Long district councillor Cheung Man-fai said Tin Fu Court and other public housing estates nearby did not have surveillance cameras and that he would raise the issue at the next council meeting.
