Gardaí have begun an investigation into the publication of material online alleged to identify the two boys convicted of the murder of 14-year-old Ana Kriégel at a derelict house in Lucan, Co Dublin last year. 

The investigation is being conducted by detectives from Lucan Garda Station where the murder investigation was centred.

Gardaí say preliminary inquiries are under way, however the investigation is expected to broaden out to include officers from specialist units, in particular the cyber crime unit and the National Bureau of Criminal Investigation.

Officers from these units have a national remit and conduct national inquiries.

It is expected that detectives will have to travel to counties all over the country as part of the investigation into the uploading and circulation of pictures purporting to be the two boys in the case.

Following court reports that the family of Boy B had been "forced into hiding", Garda Headquarters said the gardaí had no specific information in relation to any threat or allegation and had not received any complaints.

However, a garda spokesman said as an investigation was now under way into the other matters, gardaí are prepared to investigate any such complaint or allegation and the gardaí would also support any victim of crime.
