In 2019, the Offender Database confirmed that William Tierney, 52, of Blantyre, Lanarkshire, was sentenced to two years in prison at Hamilton Sheriff Court for a “sickening” sexual assault on a teenage girl. The incident took place in a hot tub in the garden of a property in Lanarkshire, where Tierney grabbed the 17-year-old victim. Despite the girl repeatedly telling him to let her go, Tierney ignored her pleas and subjected her to a sexual attack under the water.
The court heard that the victim was left severely traumatised by the assault, which occurred in what should have been a relaxed social setting. Sheriff Thomas Millar, during sentencing, noted the predatory nature of the attack and the significant psychological impact on the teenager. Tierney’s actions were described as a blatant disregard for the victim’s autonomy and physical safety.
William Tierney was sentenced to two years in prison. Under Scottish sentencing guidelines for a term of this length, offenders are typically released on license after serving half of their sentence in custody. Following his release in late 2020, Tierney remained subject to strict license conditions, meaning any further criminal behaviour or breach of supervision would result in an immediate return to prison to serve the remainder of his term.
As a result of his conviction for sexual assault, Tierney was placed on the Sex Offenders Register for ten years. He is managed by Police Scotland and the National Probation Service under the Multi-Agency Public Protection Arrangements (MAPPA). These official monitoring requirements mandate that he must notify the police of his residency, travel plans, and personal details, ensuring that authorities can track his whereabouts and intervene if he poses a risk to the community in the Lanarkshire area.
