Two men who robbed three teenagers and punched one of them with a knuckle duster have been jailed. 

Billy Presbury, 21, and Kai Warwick, 19, approached the three teenage boys in Farnham Park, Farnham Royal, on June 1, 2019. 

They stole some belongings from two of the boys and attempted to take the third boy's phone. 

During the robbery, they held a knife up to one of the boy's throats and another was punched with a knuckle duster. 

Later that day Presbury fled from police in his car when officers attempted to stop him.

When he was eventually stopped, items from the robbery were found in his car and Presbury and Warwick were also found to have cannabis when they were arrested. 

Presbury, of Moray Drive in Slough, was jailed for four years and five months in a hearing at Aylesbury Crown Court on May 12. 

He had pleaded guilty to two counts of robbery and one count each of attempted robbery, dangerous driving, having an article with a blade or point, having an offensive weapon and possessing a drug of class B.

At the same hearing Warwick, of Whiteford Road in Slough, was jailed for two and a half years. 

He pleaded guilty to two counts of robbery and one count each of attempted robbery, handling stolen goods, possessing a controlled drug of class B and having an article with a blade or point.

Investigating officer Detective Constable Stuart Cook, based at Amersham police station, said: “This was a nasty and senseless robbery against three boys, which had a detrimental effect on their mental health.

“I hope the length of the sentences will send a powerful message to the public that knife crime will not be tolerated. 

“Thames Valley Police will work tirelessly to bring to justice those that carry weapons in our communities.”
