Police Failed to Arrest Suspect Before Infant’s Tragic Death

Failure to Arrest Led to Tragedy

Cleveland police failed to arrest a man who was later convicted of sexually assaulting and killing his girlfriend’s two-year-old daughter, a court heard. Harrison Simpson had breached a non-molestation order in March 2024 but the authorities did not execute an outstanding warrant for his arrest at that time. The toddler, Isabelle Welsh, died on September 14, 2025 after what police described as a “campaign of violence” against her.

Convictions and Sentencing

Simpson was one of two people convicted in the case, along with Alexandra Walker. Both were found guilty of murder and child cruelty. Walker’s boyfriend, Simpson, who was also accused of sexually assaulting Isabelle before her death, received a life sentence with a minimum term of 28 years and six months. Walker was sentenced to 22 years in prison, minus time spent on remand.

Police Acknowledge Oversight

Cleveland police admitted that they failed to arrest Simpson after the warrant was issued in March 2024. A statement from the force explained multiple inquiries and arrest attempts were made but proved unsuccessful. The officer said, “We recognise the time Simpson had an outstanding arrest warrant is far from adequate.”

Post-Case Changes

In response to this case, Cleveland police have implemented several changes aimed at improving suspect management. This includes enhanced visibility of outstanding warrants across the force, a comprehensive data system tracking all such warrants, and stringent oversight by a governance group led by a superintendent.

Judicial Statement

The judge, Justice Norton, described Isabelle’s death as “distressing” and noted that the child had endured a “sadistic” campaign of abuse. Detective Chief Inspector Steve Chatterton, the senior investigating officer, called it one of the worst cases he had handled.

Family Statement

The family of Isabelle Welsh released a statement saying, 'Isabelle should have had her whole life ahead of her, but she was taken from us in the most heartbreaking way. She was so loved and our lives will never be the same without her.' The case highlights the critical importance of enforcing court orders to protect victims of domestic abuse.
