Social worker had throat slit in alleged attempted murder in Milton Keynes

Ruth Nyamazana, 34, said the horror attack began when Farai Kambarani shunted his car into the back of hers as she pulled into the Saxon Gate car park.

Kambarani punched her in the head 10 or 20 times then slit her throat with a silver blade as she laid on the ground.

“He moved the knife up and down, I was screaming. I thought he was going to cut my throat. The blood started gushing out,” she told a jury at Luton Crown Court.

Kambarani, aged 26, is pleading not guilty to attempting to murder Ms Nyamazana just after 8am on August 22 last year.

The court heard the couple knew each other as Kambarani was once married to the victim’s niece Tadiwa.

His wife and child left him in Wolverhampton in June last year and moved into Ms Nyamazana’s home Milton Keynes.

Two months before the attack, Kambarani had come to the house and was ‘furious and angry,’ said Ms Nyamazana.

She told the jury: “He said, ‘You have stopped me seeing my child. You don’t want me to see my child. Who do you think you are?’”

Shocked victim Ruth Nyamazana described how Kambarani slowly moved the knife up and down over her throat.

Defending, Sebastian Gardiner said his client, who moved to the UK from Zimbabwe in 2014, had simply “waved” the knife around.

But Ms Nyamazana said: “He pulled the knife slowly across my throat, up and down, up and down.”

The jury was been told Kambarani had admitted an alternative, lesser charge of wounding with intent.

He has denied a charge of stalking his wife Tadiwa between June and August last year, and also of damaging a glass panel in her door.

The trial continues.
