A former Ysgol Bro Dinefwr teacher has been banned from teaching for five years after sending thousands of sexual messages to three pupils.

Christopher Clarke contacted the girls, aged 15 and 16, at the time via Facebook, Twitter and Snapchat.

The 29-year-old also bought pupils gifts including sweets and games consoles.

One of the girls, now 19, said how he invited her to one-on-one sessions in his office and told her not to show anyone the gifts he gave her.

Police investigated but no charges were brought against Mr Clarke.

Education Workforce Council chairman, Steve Powell, said Mr Clarke's conduct "clearly breached boundaries between teachers and pupils".

The school also began an investigation but he resigned before any findings were made.
