A secondary school student was spared jail for selling drug-laced delicacies to her classmates at her school's athletics meet in Tsing Yi last year. Dora Radic, 18, was slapped with a HK$10,000 fine in Tsuen Wan Court yesterday after she previously pleaded guilty to one count of trafficking a dangerous drug involving 0.38 grams of cannabis in the form of five "hash brownies" and 22 "weed cupcakes" at Tsing Yi Sports Ground on November 3 last year.

Radic is a Form Four student at the YMCA of Hong Kong Christian College, while Richards is an ex-student who is now studying in Macau. The court heard earlier that a teacher at the school first learned about the sale of the cakes through a pupil who saw messages on Facebook. On the day of the sports event, the court heard, the teacher and a colleague found Radic and Richards, who tried to leave behind a bag when they were asked to follow the teachers. The pair also attempted to throw away some of the cakes before the police arrived, but to no avail. Police found 22 cupcakes and five brownies in the bag. Richards admitted to a deputy principal that the cakes contained cannabis, which she would sell to students contacted through Facebook for HK$25 to HK$35. She said she was offered HK$500 by a male acquaintance to sell the cakes and had sold at least 20 on the day, making HK$911.50. She admitted to police that she baked them. Meanwhile, Radic took part in sending Facebook messages with Richards, the court heard. Acting Principal Magistrate Cheang Kei-hong said he fined Radic because of her young age and her guilty plea, noting that the amount involved was small. He said of Radic, who once volunteered at a veterinary clinic: "She indicated that she was willing to assist the court and had carried out volunteer work." The Form Four student also told the court earlier that she was willing to testify against Richards, who originally pleaded not guilty. In mitigation, Philip Swainston, for Richards, said her client was under the influence of her boyfriend, who is eight years her senior. But Cheang pointed out that she once "indulged in drugs", as a report sought on her suggested. He adjourned sentencing because the report suggested she was not suitable for a probation order as she now lived in Macau.
