A JUDGE has offered a £500 reward to the mysterious stranger who bravely protected a PCSO during a 'vicious' and 'savage' attack.

Judge Peter Ross praised the 'public spirited' intervention by the unknown man who helped stop the shocking violence on the streets of Temple Cowley.

Offering the publicly-funded reward he said: "He put himself at risk and brought to an end a vicious and unpleasant assault."

Shaun Carlisle had already admitted one count of assault by beating of an emergency worker.

The 56-year-old of Oxford Road, Cowley, appeared for his sentencing at Oxford Crown Court today.

Outlining the case prosecutor Cathy Olliver said the victim - a PCSO - had left work at Cowley Police Station at about 9.30pm on May 27.

While walking to her car she saw two men 'making a lot of noise' near the library on Temple Road.

The men - one of whom was Carlisle - had been drinking.

She asked them to 'turn it down a bit' saying there were residents nearby.

Carlisle then called the woman an 'ugly b**ch' before walking towards her.

While the other man tried to calm Carlisle down he proceeded to launch an attack on the off-duty PCSO.

During the violence he punched her repeatedly in the ribs, before striking her head and ear.

After falling to the floor Carlisle continued to kick his victim three times.

An unknown member of the public then intervened and protected the woman from her aggressor.

Soon after police officers arrived; the PCSO having activated her emergency alarm on her radio.

In a victim personal statement she said she was struggling to go out and was nervous when anybody comes close to her.

It was also revealed that Carlisle has an 'extremely lengthy' criminal record, including a string of violent crimes.

He has since been recalled back to prison after his release on licence for an attempted robbery.

In mitigation at the sentencing hearing defence barrister Peter Du Feu said his client had been drinking, which he described as 'the demon' for him.

Sentencing, Judge Peter Ross said the violence was 'savage' and 'vicious.'

Carlisle was jailed for eight months for the assault and must pay a victim surcharge.

As he has been recalled on licence he is expected to serve 18-months for an earlier offence of attempted robbery as well as a count of threatening another with a bladed article.

Speaking after the hearing Emma Marshall, based at Cowley police station, said the incident had had a 'profound' effect on the victim.

She said: “This was a completely unprovoked attack on our PCSO, who was simply doing her job."

Superintendent Joe Kidman added: “This was a vicious attack on a public servant much loved by the local community she is dedicated to serving.

"A prison sentence is appropriate and necessary to show the court’s and our disgust at this individual’s actions.

“I would also like to pay tribute to the members of the public that intervened. Their actions demonstrated quick thinking and courage, doubtless preventing further harm coming to our colleague.”
