Detectives investigating the murder of a schoolgirl in Ireland have charged a 13-year-old boy.

The youth, who was arrested in connection with the death of Anastasia Kriegel, is expected to face a charge of murder when he appears before a special court sitting in Dublin on Friday evening.

Anastasia, 14, was found dead in a derelict farmhouse outside the village of Lucan, Co Dublin, last week.

The schoolgirl was last seen alive in St Catherine’s Park on Monday May 14, about one kilometre away from where her body was discovered three days later.

The boy was one of two young people arrested on Thursday. The other boy has been released without charge.

Gardai began searching for Anastasia, known as Ana, after her parents reported her missing.

She had failed to return to her home in nearby Leixlip, Co Kildare.

The teenager was a first year student at Confey Community school in the area.

Gardai began treating the death as murder following a post-mortem on her body.

It confirmed that she had died in violent circumstances.
