AMBULANCE chiefs have launched a full investigation following the death of a toddler – hours after he was checked over by paramedics and given the all-clear.

Emergency crews were called out to little Lewis Urmson-Brown’s home in Halton Brook last Sunday evening after he banged his head in a fall – but his injuries were deemed superficial.

Paramedics were then called back to the scene in the early hours of the following morning after the two-year-old’s mum found him unconscious and foaming at the mouth.

Doctors at Warrington Hospital were unable to save the youngster’s life.

A post mortem examination revealed that Lewis died of a ‘traumatic injury to the head’ – believed to have been sustained in a fall from railings at a playground near his home.

The North West Ambulance Service have since confirmed that they are investigating the circumstances surrounding Lewis’s death.

In a statement, an ambulance spokesman said: “North West Ambulance Service attended a call to a patient in Halton Brook at 19.26 on Sunday, June 15. The patient was not conveyed to hospital.

“A subsequent call was received at 03.13 on Monday, June 16. A paramedic crew attended and the patient was taken to Warrington Hospital.

“As with all clinical incidents of a serious nature, the trust has launched a full investigation into this incident.”

Police confirmed last week that they were no longer investigating Lewis’s death and were preparing a file for the coroner.

Lewis’s devastated parents Chris, aged 41, and Michelle, aged 39, who were initially arrested by police and questioned, were later released without charge.

It is understood the couple now plan to sue the ambulance service for negligence.

A spokesperson for Cheshire Police confirmed: “Investigations into the death of the two-year-old have concluded that his death was a tragic accident.”

Emotional tributes have poured in for Lewis and his family on the World’s website Michelle’s heartbroken sister, Sharon, posted: “I can't believe Lewis is gone. Our hearts go out to you both. We will support you all we can. Anna and Lucy have even named a star in the sky ‘Twinkle Lewis’. We love you.”

Another World reader, Maggie Fowler, wrote: “I’m devastated for Chris and Michelle – you are such lovely people. God bless Lewis."

And Abigale Evans, of Palacefields, posted: “Lewis was such a bright, cheerful little boy who was always smiling. It breaks my heart to know he died so young and still had so much of his life to live. Rest in peace little angel.”
