Teen sentenced for defilement of 12-year-old girl in Dublin
A 15-year-old boy in Dublin engaged in sexual acts with a 12-year-old girl near his home, an offence that came to light when the girl told a friend who alerted her mother. The boy, now 17, pleaded guilty to defilement in early 2024 and to possession and production of child sexual abuse material at the Children's Court. The case was sent to the Central Criminal Court, where Mr Justice Paul McDermott in October 2026 sentenced him to a two-year detention order, with eight months in detention and the final 16 months suspended for three years.
