A 'VENGEFUL' mum-of-six shouted 'die, die, die' as she filmed herself pouring household bleach into a tropical fish tank belonging to her 'selfish' ex-boyfriend.

Serena Reynoldson was given an 18-week suspended prison sentence and banned from keeping fish for life when she appeared at Oxford Magistrates’ Court on Tuesday.

The 35-year-old of Sealham Road, Ducklington, near Witney, was furious that John Fitzpatrick had left her to deal with their four children and family pets after an alleged affair.

She filmed herself pouring the poisonous substance into a tank belonging to her former partner in January and sent him the video as a WhatsApp message.

The clips below, which were provided by the RSPCA and show Reynoldson describing what she is doing before the fish can be seen dying in the tank, were then sent to her partner who contacted the police. 

Warning: some people may find this video distressing.

Reynoldson can be seen holding an open bottle labelled thick bleach in the video.

She said: "Seeing as it’s okay for you to have your hobbies but I can't have mine, bleach right in there."

She then pours the bleach into the tank, saying "eat it, drink it, good" as the fish swim towards the chemical adding: "die, die, die."

Reynoldson continued: "If I can't have no hobbies or a life you can't have them and I'm not paying for it."

She proceeds to taunt her ex-boyfriend as the fish start to float to the surface of the water calling him 'selfish' as she continues to add bleach from a second bottle.

Oxford Magistrates' Court heard how Mr Fitzpatrick had moved out after she accused him of having an affair.

This left Reynoldson - who has five children under the age of ten - along with the children, a cat, a snake and the tropical fish.

Mr Fitzpatrick called police after the incident on January 9 and the RSPCA were called in.

She had sent two WhatsApp videos to her ex-partner threatening to harm the animals with rat poison.

Reynoldson told police in an interview that she did not know what the liquid was and she did not know what the consequences would be.

She admitted a charge of causing unnecessary suffering to protected animals.

RSPCA inspector Andy Eddy, who investigated for the animal welfare charity, said: “It’s shocking that the fish were killed during this deliberate vengeful intentional act.

“These fish would have suffered needlessly because of the levels of chlorine and ammonia being poured in the water by Serena Reynoldson.

“There is never an excuse for such heartless and unpleasant behaviour, or for showing such a lack of empathy towards any animal by behaving in this way.”

Reynoldson was also ordered to pay £415 in court costs.
