A mother-of-four who collapsed in court moments after a hearing a family court ruling received no treatment for four minutes when a paramedic arrived before she died, it was revealed today.

Hayley Gascoigne suffered a cardiac arrest as she sat in the concourse next to her parents Terry and Kathleen at Hull Crown Court on January 26.

Today a damning Yorkshire Ambulance Service report revealed the 32-year-old was not treated straight away when the rapid response vehicle (RRV) came and the paramedic should have used a defibrillator because she had a 'shockable' heart rhythm. 

The error was compounded by two more paramedics in an ambulance who did not challenge this decision. 

Hayley died in her sister's arms because of the 'stress' of a ruling in a family legal battle involving children, her devastated father told MailOnline the following day.

Her parents, who care for her four children, said today: 'Hayley was let down badly by the people whose job it was to help her, and we feel very frustrated and sad about this.

'We are deeply upset by our daughter's untimely death and miss her very much every day. Hayley was a fantastic mother who adored her children.' 

The ambulance report said there was a 'degree of mismanagement' in her case. After a post-incident debrief, which identified 'mistakes had been made', the RRV paramedic and ambulance paramedic who arrived later were suspended from frontline duties, although the latter was reinstated in a day. Records showed a 'noticeable decline' in regular, structured training for the RRV paramedic after 2011. 

Police initially launched an investigation amid concerns from a relative that she may have 'taken something' in the toilet shortly before she became ill. But a post-mortem examination has revealed found she died of hypertensive heart disease - often caused by high blood pressure - and toxicology tests all came back negative - meaning there was no trace of any drugs or alcohol found in her system.

The young mother, from Scunthorpe, Lincolnshire, fell ill while sitting with relatives on the first-floor concourse of the court just before 3pm on January 26.

Her mother Kathleen was heard screaming: 'Hayley. Oh My God. Call an ambulance. Please save her please.'

Miss Gascoigne began convulsing and was rushed to hospital but could not be saved - her parents had to break the devastating news to the children.

Paramedics arrived and she was taken to Hull Royal Infirmary, but was later pronounced dead.

Speaking at his home in Scunthorpe her father Terry Gascoigne said: 'My daughter died in my other daughter's arms. She died because of the stress'.

Some of Miss Gascoigne's friends posted Facebook tributes to the mother of four.

One said: 'She was a lovely, warm kind person and this is just so tragic. Love n strength to all her family n friends.'
