A teenage girl is suing her former private school for allegedly failing in its duty of care after she was left with PTSD following a weekend of drinking and smoking a vape laced with a powerful synthetic drug.

Irune Pedrayes was only 14 and in her first weeks at the £34,000-a-year Buckswood School when she was supplied with vape liquid containing the stimulant mephedrone by senior boys at her school.

Miss Pedrayes, now 19, claims she spent a weekend vaping the Class B controlled substance and drinking with others on the rugby pitch at the school, which is near Hastings in East Sussex.

But the binge landed her in hospital after she suffered an extended 'psychotic outbreak' for which she blames the school's alleged lack of safeguarding - a claim denied by its lawyers.

Her parents were not told and the breakdown continued for weeks until she left the school to return to her native Spain, where she received antipsychotic medication.
