A woman has been charged after allegedly poisoning a co-worker's lunch curry with snail pellets at a workplace in Perth's southern suburbs.
Western Australian police say a 58-year-old woman brought a container of curry to share with colleagues in February. A 43-year-old woman then allegedly contaminated the dish with snail pellets containing metaldehyde, a poisonous substance, according to a police spokesperson.
The curry had been shared among employees and consumed without issue during a morning tea break, police said. After the meal, the accused allegedly accessed a chemical storage shed and later entered the staff lunchroom where the food was kept.
At lunchtime, the alleged victim returned to eat more of her curry. When she opened the container, she spotted bright green granules in the food.
"After tasting a small amount, (she) experienced numbness to her tongue," the police spokesperson said.
It will be alleged the accused and the victim were in a personal relationship.
Detectives arrested the woman last week. She has been charged with one count of unlawful act or omission with intent to harm (endangering the life, health or safety of any person) and is scheduled to appear before Armadale Magistrates Court on 5 November.
Police declined to provide further information about the relationship or the workplace.
