article: Fireman Stephen Hunt, 38, died after he and a colleague got into difficulties battling a fire started at Paul's Hair World in Manchester's Northern Quarter on July 13, 2013 . A 16-year-old girl charged with arson after she discarded a cigarette causing a city centre shop blaze which claimed the life of a firefighter had the charge dropped today after a judge said she was 'guilty only of being careless'. Fireman Stephen Hunt, 38, lost his life tackling the inferno which began at Paul's Hair World in Manchester's Northern Quarter almost two years ago. The girl - who was just 15 at the time - is said to have dropped a cigarette to the floor while standing near the shop's fire exit which rolled underneath the door and set boxes alight. She was originally charged with arson being reckless as to whether life was endangered, but was cleared having been due to stand trial on Monday. After more than a year of legal wrangling, with scientists initially stating that the fire could not have been started accidentally, further investigation led to the conclusion a discarded cigarette could have been the cause. More than 60 firefighters battled the blaze, which erupted on July 13, 2013, as frightened passers-by watched on. Father-of-two Mr Hunt, of Whitefield, Manchester, and another fireman, got into difficulties while tackling the fire and they were rushed to hospital where Mr Hunt was pronounced dead. At Manchester Crown Court, prosecutor Alexander Leach said thin and damaged cardboard boxes and paper labels stored behind the fire door at the business may well have caught fire if a cigarette was discarded. He said: 'Combined with the suggestion that boxes may have been on top of the smouldering cigarette, compressing and containing the heat, this made it more likely items would ignite. The salon was totally gutted when an inferno started by a discarded cigarette ripped through it. The 16-year-old girl who started the fire was today told she will not face trial for arson as she had only been 'careless' The family of Stephen Hunt visit the scene where he died.

Firefighters enter the remains of music venue NQ Live in Manchester which was also destroyed by the fire (left). Dozens of floral tributes to fireman Stephen Hunt were left at the scene (right) 'It was a hot day and there was a gap beneath the door and as a result experts were unable to exclude a chimney effect as air was drawn under the gap underneath the door and the fire began. 'The conclusion is the Crown's case, which had previously been based on scientific evidence which excluded accidental ignition, can no longer be sustained, so I offer no evidence.' The teenager, who did not attend court, was initially arrested along with another 15-year-old girl but she was the only one charged. Throwing the case out, Judge Michael Henshell said: 'I spent some time reading the papers and reports and it is perfectly obvious this terrible and tragic case demonstrates the danger and potential danger from discarded cigarettes. A fireman patrols the scene in Manchester's Northern Quarter where his colleague was killed. More than 1,000 firefighters, emergency service staff and members of the public lined the streets of Bury for Mr Hunt's funeral . More than 60 firefighters battled the blaze, which erupted on July 13, 2013, as passers-by watched on . 'This was discarded without any thought and as a result a fire started in circumstances which were particular to the site in question, resulting in extensive damage and costing the life of a man who, as part of his employment, was there to protect life and property. 'It was a terrible consequence for a thoughtless act. The girl who had been charged and faced trial was, in fact, blameless so far as criminal law is concerned and guilty only of being careless.' In September 2013 more than 1,000 firefighters, emergency service staff and members of the public lined the streets of Bury for Mr Hunt's funeral. In a tribute to him at his funeral, his son Sam said: 'To me, he wasn't just my dad but my hero, my role model and my best friend.' Following the hearing today, a spokesperson for Greater Manchester Fire and Rescue Service said: 'We have made no comment on any aspect of the incident and are unlikely to do so until the coroner's inquest into Stephen's death has concluded. 'Safe to say we continue to work with everyone involved in various investigations to find the truth of what happened, not least for Stephen's family but for everyone involved and especially our firefighters.'
