A pupil at a school which has banned fatty drinks and snacks has been suspended for "crisp dealing"
Joel Bradley, 12, was caught allegedly selling a packet of Discos at a marked-up price of 50 pence.
The student at Liverpool's Cardinal Heenan High School was given a day's suspension because it was the second time he had been caught.
His father, Joe, told the Liverpool Echo the youngster was being "victimised" for the enterprise, which could earn him as much as £15 a day.
Mr Bradley, from Norris Green, admitted he too had once been caught selling canned drinks, chocolate bars and crisps from a van outside the school.
He said: "I think the school has made a beeline for him because of what I've done."
Cardinal Heenan's head teacher Dave Forshaw said: "We are a healthy school and proud of it.
"If parents are not happy then they are perfectly free to take their children to a school that allows pupils to sell these things and allows a father to sell them outside on the pavement."
The headteacher said pupils were caught around "three or four times a week" selling snacks at the school.
"We have six to seven regular sellers we pinpoint", he said.
