An 18-year-old woman who murdered an admirer by stabbing him in a "fit of anger" in his car has been jailed.

Martyna Ogonowska attacked Filip Jaskiewicz after he tried to touch her sexually, in Peterborough in October, before she fled to an ex's house.

She claimed she went to punch Mr Jaskiewicz, 23, but "forgot" she was holding a knife, which punctured his heart and killed him.

Ogonowska was given a life sentence and will serve a minimum of 17 years.

She was found guilty by a jury at Cambridge Crown Court of murder and possessing a bladed article.

Prosecutor Andrew Jackson told jurors the pair had met three days earlier and Mr Jaskiewicz "hoped a relationship would develop".

After a night out at Solstice nightclub in the town, Ogonowska, Mr Jaskiewicz and two friends stopped at about 04:00 BST on 21 October in Oakdale Avenue, where an argument broke out the speed at which he had been driving.

Poland-born Ogonowska, of Peterborough, told the court she "got nervous, left the car and slammed the door".

But Mr Jaskiewicz followed her and grabbed her neck, forcing her to her knees, actions which Judge David Farrell QC described as an "assault".

The mother-of-one had said in evidence the pair returned to the car, where he "started to be aggressive towards me again" and tried to touch her breasts.

Judge Farrell said Ogonowska "became annoyed - you wanted attention and showed him the knife" she had been carrying over the course of the evening.

"You then, in anger, deliberately stabbed him intending to cause him at the very least really serious bodily harm," he told her.

In police interview she said she "forgot" she was holding the knife, and called the murder an "accident".

Judge Farrell acknowledged there had been "provocation" and Mr Jaskiewicz had "undoubtedly touched you sexually and was violent towards you" - but said there was "no reasonable self defence when you used a knife you brought to the scene".

After stabbing him through the heart she ran away to her ex-boyfriend's house, where she washed the knife and changed her clothes, the court heard.

She later turned herself into police, but before that had messaged her mother, who had also been on the night out, and said: "The whole knife went into his heart... Mum, what should I do?".

Ogonowska was also sentenced to 18 months for possessing a bladed article, to run concurrently.
