Being forced to eat dog biscuits off the floor was part of life for young children at an educational referral unit, former pupils have said.
One was left with a fear of football after being pelted with "rock-solid" ***** , while another had a pint of blackcurrant juice poured over her head.
And they say this wasn't even punishment - it was fun for the staff. When pupils were disciplined at Canolfan Brynffynnon in Y Felinheli, some could also expect to be locked in a dark toilet or have their nose flicked until it bled.
Cyngor Gwynedd admitted abuse took place and has apologised to victims while two former staff members allegedly involved have strongly denied the allegations.
Rhiannon Evans, who was 10 when she was sent, and Levi Lewis, who was four, are among 21 people who solicitor Katherine Yates said are currently pursuing claims.
