FRIGHT NIGHT: While bars and restaurants in Lan Kwai Fong are decking themselves out for tonight's Halloween celebrations, police are making security preparations following the recent terrorist attack in Bali. Up to 20,000 people are expected to join the festivities and a police spokesman said the area would be closed to traffic from 5pm to ensure public safety. 'As large numbers of people are expected, those wishing to enter the Lan Kwai Fong area may have to queue and wait to gain access,' he said. Lan Kwai Fong Association chairman Richard Feldman said he anticipated attendance levels would drop by 30 per cent if the rain continued, as forecast. He added that the area already had good security arrangements following an incident on New Year's Eve in 1993, in which 21 people were crushed to death. A Lan Kwai Fong Entertainment spokeswoman said: 'To be honest, we are not concerned about terrorism at all. We don't think Hong Kong or Lan Kwai Fong will be attacked.'
