Michael Hurley begged her to start breathing as officers gave the 15-year- old emergency first aid. The youngster was standing 10 feet from suicide bomber Salman Abedi when he detonated a bomb that killed 22 and left hundreds injured. Megan had been at an Ariana Grande concert with her brother, Bradley, 21, when they were caught in the blast in 2017.

       Bradley was seriously injured and knew he was “helpless to try to save his sister” the inquiry heard.

       Their parents, Michael and Joanne Hurley, from Halewood, Merseyside, were on their way to collect their children after the concert when Mr Hurley called his son.

       Mr Hurley found Megan but could not detect a pulse and called out to police to help. An officer, identified only as F2, said: “Give me a sec I think I have got a pulse.”

       The officer started cardio-pulmonary resuscitation (CPR) with PC Owen Whittell giving mouth-to-mouth.

       The officers worked in tandem, using a defibrillator in between chest compressions and mouth-to-mouth, with Mr Hurley shouting: “Come on Meg.”

       The Manchester inquiry heard that after three minutes PC Whittell shouted, “Right, stand clear please. Clear!” as the defibrillator was used again before CPR and more breaths were administered.

       On body-worn cameras Mr Hurley could be heard shouting again, “Come on Megan, love.”

       Another first aider said Megan had suffered a “catastrophic bleed” and advised the officers to try to treat other injured people.

       But Police Sergeant Kam Hare replied: “We are not calling it yet mate. We will do one more.”

       CPR was given again. Shortly after, paramedic Patrick Ennis was called over to assess Megan but said: “Unfortunately she’s dead.”

       Following a post-mortem, assessment by blast wave bomb experts and forensic pathology experts had concluded that Megan’s injuries were “unsurvivable”.

       Sir John Saunders, chairman of the inquiry, remarked on the “evocative” portrait photo of Megan, shown on screens at the hearing. He said: “Everyone here understands why her father was so reluctant to let her go.”

       The inquiry is looking at how and in what circumstances the victims died and whether inadequacies in the emergency response contributed to deaths.

       The hearing continues.
