MR Justice Bokhary is considering a late night tour of Lan Kwai Fong to get an idea of the scene in full swing as part of his inquiry into the New Year tragedy that left 21 people dead. Mr Justice Bokhary's assistant, Mr Paul Wong Pow-ah, said it would be impossible to stage a reconstruction of the events so thought was being given to a late-night tour. ''It's important to look at these things from every angle but we have to face facts that it would be impossible to recreate the scene exactly,'' Mr Wong said. ''We're certainly getting a good idea from the videotapes we have from two television stations and members of the public of what happened on the night,'' he said. Highways Department officers have provided on-scene skid tests on the cobbled streets of Lan Kwai Fong, spraying cans of foam and spilling beer to recreate the surface on the night. Yesterday, Mr Justice Bokhary spoke to witnesses in Tang Shiu Kin Hospital and studied police logs. ''When the weekend's over we've got seven days to put the preliminary report to the Governor, so thought has to now be given to what recommendations will be made,'' said Mr Wong. Meanwhile, the Fire Services Department yesterday defended the absence of any ambulances on standby at Lan Kwai Fong on the night of the tragedy. Department director Mr Lam Chek-yuen said ambulances were not sent to places where people were expected to gather unless there were requests from organisers. No one party was responsible for organising the festivities, he said. ''It was unlike events such as the Lunar New Year Flower Market in Victoria Park or some big football matches, which have organisers that you can talk to and see if emergency services are needed,'' he said. Future arrangements would be influenced by the interim report. He admitted that the first ambulance had taken 10 minutes to reach the scene, ''somewhat longer than past cases''. It was caused by traffic congestion and crowds blocking the roads. But he was satisfied that all the crews had done everything they could to help save lives. Six people injured in the stampede were still in hospital last night - one man was in a poor condition, one man fair, and the remaining three men and a woman satisfactory.
