Spurned pharmacist admits spiking co-worker's drinks to make her 'suffer'

A Sydney pharmacist has admitted spiking a co-worker’s drinks to make her suffer for refusing his advances.

Yan Chi “Anthony” Cheung faced court in Sydney today accused of secretly placing a range of drugs into Pamela Leung's drinks over an extended period.

Anthony Cheung pleaded guilty in the Waverley Local Court on Tuesday to placing drugs in the 26-year-old’s coffee and water every couple of weeks for a year.

The drugs he used included phernagan, doxylamine, endep and seruguel, which can cause infertility and drowsiness among other effects.


Court documents say Anthony Cheung became infatuated with Pamela Cheung after the pair met at Surry Hills Presbyterian Church.

Police claim Anthony Cheung became infatuated with the victim over the subsequent three years, with the relationship taking a sinister turn after Pamela Cheung rejected the man’s advances.

Court documents said Anthony Cheung had made a series of sexual advaces towards the victim, including brushing against her breasts and buttocks, which she found 'rude'.

Anthony Cheung, who is married, was accused of using his detailed knowledge of the drugs to take revenge on the woman.

The effects of the drugging left her struggling to work, requiring regular rests or needing to go home where her husband would often find her unresponsive.

“When asked why he had admitted to having used the drugs against the accused he stated that he wanted the victim to suffer,” court documents stated.

The victim, having become suspicious, asked Anthony Cheung to teach her to use the business at the UNSW campus’s CCTV system to discover why she had noticed bitter tastes in her drinks and a numb tongue.

Anthony Cheung’s guilty plea meant a charge of evidence tampering was dismissed.

He has been released until a sentencing hearing set for next month with an AVO preventing him coming within 50 metres of his victim.
