A teenager who stabbed her mother's partner after a history of domestic abuse has been cleared by a jury of attempted murder.

Shanice Myers, 19, attacked her mother's partner Daniel Paul armed with two knives on the evening of May 5.

Myers has told Norwich Crown Court of a history of abuse and violence Mr Paul used to inflict on her mother.

And under cross-examination on Thursday, Myers said she feared he was "going to end up doing something terrible to her" when she heard them arguing.

"Both of them was arguing and it was getting aggressive and heated," she said.

Myers said she feared if she had armed herself with just one knife Mr Paul could have disarmed her.

"If he could get it off me I would end up dead, or my mum," she said.

"I had no intention to kill Mr Paul. My main focus was to stop him hurting my mum. Not to kill."

She said the attack had been "frenzied" and was over in "a matter of seconds".

"He was trying to grab the knives out of my hands and I was going quite quickly," she said.

"I did not have a set place for where I wanted to stab him.

"There was no control or thoughts of what was happening in that moment. It happened frantically.

"I went in thinking he is not going to be able to retaliate and hurt us.

"The reason is was so frenzied and frantic is he was trying to grab my wrists and my arms.

The court had heard how Myers' mother had been given a disclosure of Mr Paul's domestic violence history under Clare's Law, including a restraining order against a previous partner.

But she did not want to pursue a prosecution despite multiple calls to 999 and reports of violence.

"I wanted him to leave the home and be far away," said Myers.

"I rang police on multiple occasions crying for help. My mum couldn't meet them halfway so it just carried on and got worse."

Myers, of Proctors Close, Kings Lynn denied attempted murder and an alternative charge of wounding with intent during a four day trial this week.

A jury of nine men and three women found Miss Myers not guilty on both counts after around seven hours of deliberation.
