Parents of pupils at a secondary school in Cardiff are consulting solicitors amid fears their children may have been filmed in secret at a toilet in their school.
It follows guilty pleas to voyeurism by the deputy head teacher at Ysgol Glantaf last month involving a hidden camera at another location.
Police have been carrying out further investigations at the school as Gareth Williams awaits sentence.
That has prompted some parents to seek legal advice.
