The man widely known as the Prince of White Flower Oil was partying at a wedding in Wan Chai on the night he was accused of molesting a taxi driver four years ago, the bride told a court yesterday. Denise Lau Sze-wai was testifying in Eastern Court at the trial of Stephen Gan Fock-wai, chief executive of Pak Fah Yeow International, the maker of traditional Chinese analgesic balm and other products. Gan has pleaded not guilty to two counts of indecent assault. A taxi driver, 37, earlier testified that Gan fondled his private parts inside a cab at about 1am on November 30, 2003, on Braemar Hill Road. But both Ms Lau and Gan's younger sister, Gan Fock-yin, testified yesterday that Gan was at the wedding party at that time. Ms Gan told the court she drove her brother home after the wedding and saw him enter the gate of his housing complex shortly after 2am that night. Gan says he has no memory of the day's events. Gan, 46, who acknowledged in court earlier this week that he was bisexual, has also denied he harassed another taxi driver, 34, on October 10, 2006. He says that driver did not object when he touched his crotch and that he believed the driver was sexually interested in him. The trial, which has dominated headlines, was due to end yesterday but instead took a surprising twist when the defence applied to call two 'strong' alibi witnesses after one of them read Wednesday's news reports in the Post and Apple Daily and found them 'odd'. Ms Lau, a socialite and chief operations officer of building material supplier BSC Group, was reading the newspaper accounts when she realised that one of the alleged assaults was on the same date as her wedding party. She called Gan's younger sister, Gan Fock-yin. Two photos showing Gan, his two younger sisters and their mother at the banquet at Grand Hyatt were submitted to the court. Ms Lau said that after the banquet ended, she went upstairs to a party in the hotel's presidential suite at about 1am. Gan was inside the suite with his sisters. She said she had a strong recollection of the events, in particular because Gan had complimented her, saying it was the best wedding he had attended. But she did not know when he left because she had been busy mingling with guests. Ms Gan, who was Ms Lau's bridesmaid, said she went to the suite at about midnight to prepare for the party and waited for an hour for the bride to turn up. Her brother, she said, was in the suite with her until their younger sister asked to leave a little after 2am. Ms Gan then drove her two siblings home and she returned to her own home at 3am. Following the two witnesses' evidence, the taxi driver was recalled to the witness box and asked to comment on the new evidence. Lawrence Lok Ying-kam SC, for Gan, accused the driver of fabricating the molestation claim. However, the driver said his memory was correct because the assault had been on his mind ever since it happened. Magistrate Winston Leung Wing-chung has ordered that the names of the two taxi drivers be suppressed. Mr Leung will hear submissions next Friday. Gan has been freed on HK$2,000 bail. Gan, known as the Prince of White Flower Oil because he is spokesman for his family business' products, appears in all advertisements for the products and sings their jingles.
