Extra security guards were called in yesterday to ensure that potential buyers of Residence Bel-Air, the deluxe residential part of Cyberport, were not pestered by property agents. Drastic measures have also been taken by the developer to fine and ban any agents who use heavy-handed sales tactics such as blocking the paths of vehicles or chasing cars. 'The whole team from the property agent branch will have their agency agreement terminated if any of their members breach the rules. And we will carry out the new policy very strictly and seriously,' warned Vivian Sze Mo-lan, Cyberport's deputy sales and marketing director. Under a new arrangement, property agents were required to queue and wait for potential buyers instead of chasing them outside the sales office. Last week the South China Morning Post reported that police had received a series of complaints from residents and drivers against the property agents. Ms Sze said the new arrangements resulted from a series of meetings with police, the Estate Agents Authority and four major property agents. The developer has increased the number of security guards at the site from 35 to 43. Six police officers and two police vans were outside the sales office at lunchtime yesterday. Dozens of property agents were waiting quietly outside but none of them dashed out to meet cars - in contrast to a week ago. Property agent Danny Lam from Hong Kong Property said he had been warned of the rules by his supervisor, 'and we have to follow them strictly'. Jacky Yip Siu-kwong from Centaline Property Agency said: 'It is not our company policy to chase after cars. But our branch manager kept reminding me not to do it over the last few days.' Angelina Lee, a resident of Mount Davis who had called police after claiming her car was surrounded by 10 agents a week ago, said the situation had improved. 'They still approach cars and hold signs to attract businesses, but they are much better-behaved and less aggressive,' she said. The Bel-Air project comprises 2,800 flats in five phases to be completed by the end of 2007.
