Cleveland police failed to arrest a paedophile for breaching a non-molestation order, 18 months before he sexually assaulted and murdered his girlfriend’s two-year-old daughter. This tragic case highlights critical failures in the justice system and police procedures that allowed a dangerous offender to remain free, ultimately leading to the death of little Isabelle Welsh.
What Happened in the Cleveland Police Case?
Isabelle Welsh died on 14 September 2025 after what police described as a “campaign of violence” against her. The two-year-old collapsed at her home in Teesside after weeks of abuse that left her covered in bruises and with 21 broken bones. Her mother, Alexandra Walker, 26, and her boyfriend, Harrison Simpson, 22, were convicted of murder and child cruelty on Thursday after a trial at Teesside crown court.

Simpson was also convicted of sexually assaulting Isabelle before her death. Walker was cleared of that charge. The pair were jailed for life, with minimum terms of 28 years and six months for Simpson and 22 years for Walker, both minus time spent on remand.
The Missed Arrest Warrant: A Fatal Oversight
Cleveland police admitted that officers failed to execute a warrant issued by Teesside magistrates court for Simpson’s arrest in March 2024. Simpson had failed to attend court for breaching a non-molestation order, which is an injunction designed to protect victims of domestic abuse. It is understood the non-molestation order was in place after reports Simpson had harassed and threatened a woman.
The police’s failure to arrest Simpson allowed him to continue his violent behavior, which escalated to the horrific abuse and murder of a toddler. This case raises serious questions about how outstanding warrants are managed and why a known offender was not apprehended despite multiple inquiries.
Police Response and Systemic Changes
Cleveland police said in a statement: “Multiple inquiries and arrest attempts were carried out to try to locate and arrest him, but these proved unsuccessful.” They added: “We recognise the time Simpson had an outstanding arrest warrant is far from adequate. A review of this was immediately conducted upon his arrest for murder.”
“This review, along with a determination to continually improve our processes around suspect management, has led to a number of recent changes, such as ongoing improved visibility across the force around outstanding warrants, a comprehensive data system which tracks all outstanding warrants, and stringent oversight.”
Key Takeaways from This Tragic Case
- Warrant failures can have fatal consequences, as seen in this Cleveland police case.
- Non-molestation orders must be enforced promptly to protect victims of domestic abuse.
- Police accountability is critical to prevent future tragedies.
- Systemic changes, such as better warrant tracking, are necessary to close gaps in the justice system.
