A boy was arrested in connection with the death of schoolgirl Anna Kriegal this morning.
He is expected to appear before Dublin District Children’s Court at 10:30am and charged in connection with the investigation.
Another boy (13) has already been charged in connection with the murder and was refused bail by High Court.
Both boys cannot be named because they are minors.
Anna left her house in Leixlip around 5pm on the 14th May but did not return.
She was found, beaten to death, three days later in a disused farmhouse.
