Paedophile headteacher may have abused since 1979
Four times as many victims as previously thought may have been targeted by paedophile headteacher Neil Foden.
A BBC Wales investigation found allegations going back to 1979.
One former pupil, who we are calling Jo, said Foden, who was employed by Cyngor Gwynedd, messaged her until he was arrested.
Another said: "I know he was doing it in 1979 because he was doing it to me."
