A 'lesbian' housewife robbed a florist of her fake Rolex watch by threatening her with a blood-filled syringe, saying it was contaminated with the Aids virus, a court heard yesterday. So Mei-kuen, 32, has denied one count of robbery. Tam Kam-lin told the District Court that So entered her flower shop in the Hong Lai Commercial Complex, Tuen Mun, on October 27 last year and ordered a bouquet. But while Ms Tam was wrapping the flowers, So, who claimed to be a lesbian, pointed a blood-filled syringe at her neck. Ms Tam said So demanded her watch - a gift from her ex-husband which she believed was a genuine Rolex brand. She also told Ms Tam the blood inside the syringe was infected with the Aids virus (HIV), the court heard. Ms Tam said she struggled with So and managed to grab the syringe and throw it out of the shop, but So had already taken her watch and fled. Defending herself, So said she went to the shop to buy flowers but denied saying she was a lesbian. She said she was a housewife with a three-year-old son. So told the court she had injected heroin in a public toilet shortly before and had not disposed of the syringe. She testified she had a fight with Ms Tam, who she believed looked down on her because she appeared to be an intruder without money, and during the struggle the syringe fell from her bag. Judge Bernard Whaley will give his verdict today.
