Photography teacher Julian Fawkes assaulted boy at Talybont
A college photography teacher has been convicted of assaulting a 13-year-old boy after leaving a Gwynedd caravan park.
Caernarfon magistrates heard that Julian Fawkes, 36, from Birmingham, wrongly believed the youth had picked up his wallet after he drove away from the site at Talybont near Barmouth.
Fawkes denied losing his temper and pushing the boy against a wall.
He was bailed for sentencing next month.
The court heard that Fawkes, who teaches at Birmingham's Metropolitan College, thought he may have left his wallet on the top of his car as he drove away.
Magistrates were told that he then spotted the 13-year-old with a wallet, and approached him.
The defendant insisted that he remained calm and polite, removed the wallet from the boy, and then returned it and apologised, shaking the teenager's hand.
However, finding him guilty, the court chairwoman said the boy and an adult eyewitness gave consistent and credible evidence, and Fawkes used force which was "out of all proportion."
The defendant was told an "all-options" pre-sentence report would now be prepared for the court.
