Two teenagers have been jailed for 18 months after breaking a man's jaw in an Epsom park.

Connor Peach, 18, now known as Gallagher, of Woodfield Close in Ashtead and a 17-year-old boy were part of a group who became involved in an argument with the victim in McDonald's in the High Street at about 10.45pm on November 28, 2014.

They followed him away from Epsom town centre before attacking him in Roseberry Park. 

A member of the public, who was visiting a church nearby, saw the victim in an "extremely distressed" state being chased and decided to intervene.

Surrey Police officers believe her bravery stopped the attackers and prevented the attack from being far more prolonged.

She has now been nominated for a High Sheriff's award.

Detective Constable Jody Newman said: "This was a really nasty assault which began with a verbal exchange at McDonalds and ended with the victim being beaten so severely that he was left with a broken jaw on both sides of his face.

"His injuries were only prevented from being far more serious, and the attack far more prolonged, by the member of the public who stepped in and confronted the attackers.

"Her extreme courage has been recognised with a nomination for a High Sheriff’s award.

"Following the assault, we carried out a lengthy and thorough investigation, which included the release of a media appeal with CCTV images from the night in question which led to the 17-year-old being identified, arrested and subsequently charged."

DC Neman added: "This would have been a terrifying incident to have witnessed and we would like to thank all those who came forward as a result of the media appeal, without which we would not have been able to bring the two suspects to justice."

The pair were jailed at Guildford Crown Court on Friday, February 3.
