A woman who regularly complained of feeling ill at work and noticed a peculiar taste in her drinks had allegedly been poisoned by a co-worker for months.

Police arrested a 33-year-old man on Thursday in Maroubra, in Sydney's east, after the woman told officers of her suspicions, news.com.au reported.

The pair worked together in a Sydney pharmacy and while they had never been in a relationship, the man was "infatuated' with the 26-year-old, reported the ABC.

Police viewed CCTV footage which they say allegedly shows the woman's colleague pouring a liquid substance into her drink. The investigation was sparked on Wednesday when she reported suspicions that a colleague had placed drugs in her drinks.


Police said the assistant pharmacist noticed her drink tasted "bitter" on a number of occasions while at work.

The pair are said to have met at a local church with the man subsequently offering her a job at the pharmacy

The man was charged with using poison to injure or cause distress or pain, and tampering with evidence and will appear at Waverley Local Court on 24 May
