A 14-year-old boy is being questioned about an alleged rape at a teenage disco in Dublin last night.

The boy is being detained at Terenure Garda Station.

He was arrested at Tramco nightclub in Rathmines at around 11.30pm after a 15-year-old girl alleged she had been raped in the toilets.

The nightclub, which was hosting a disco for Junior Certificate students, was immediately closed and sealed-off.

The boy is being questioned today in the company of his parents. He can be questioned for up to 24 hours.

A garda forensic team carried out a technical examination at the scene this morning.

The girl was taken to the Sexual Assault Treatment Unit at the Rotunda Hospital.
