One of Ireland’s most prestigious girls school is under investigation for lesbian sex abuse, according to reports.

The Health Service Executive (HSE) West is looking into allegations of inappropriate sexual activity at Kylemore Abbey school in County Galway, in the West of Ireland.

The claims date back 20 years at the top tourist attraction, which is run by Benedictine Nuns, the Irish Independent reports.

None of the current employees or students are believed to be involved.

The paper claims that a church investigation forwarded stories of alleged sex abuse to the Vatican in the 1980s, but no charges were brought.

The Irish police and the Western Health Board, later replaced by the HSE, were not informed at the time, but have now intervened after the nuns called them in.

HSE West has confirmed an investigation is under way, although no one has made an official complaint and there are no specific details of the alleged abuse.
