A jealous woman has been arrested for poisoning her ex-partner and his new fiancee with a tampered box of chocolates a few days before their wedding.

The incident took place in the municipality of Jaiba in the Brazilian state of Minas Gerais on 23rd September.

According to the news site G1, five people were poisoned by the chocolates and were hospitalised after falling sick. Meanwhile, the family dog, also given a sweet or two as a treat, died as a result.

The police learned that two victims were due to be married over the weekend. The other three victims were two adults and a two-year-old child.

A woman, name not disclosed, was arrested a day after the alleged poisoning incident. She was later identified by the police as the ex-girlfriend of the groom-to-be.

The police said that a taxi driver delivered the gift, consisting of chocolates and some glasses, that was addressed to the bride.

Believing it was a wedding gift, the group tucked into the choccies and the dog was the first to fall sick, according to reports.

After interviewing the victims and other family members, the police identified the groom’s ex-partner as the main suspect.

According to their statements, the woman was never able to accept the end of the relationship or that her ex had found happiness with someone else.

No information has yet been released about the substance used in the chocolates and the incident remains under investigation.
