An eight-year-old survivor of the Manchester Arena attack has been reunited with the police officer who helped save her life.

Lily Harrison suffered a shrapnel wound and a bruised lung after being thrown to the floor by the suicide blast.

Her parents were also injured in the attack which killed 22 people at the end of an Ariana Grande concert in May.

Pc Cath Daley rushed Lily to hospital in a police van as it was feared she would have died had she waited for an ambulance to arrive.

At one stage Lily's mother thought her little girl was dead as she fell in and out of consciousness.

In emotional scenes to be aired tonight in an ITV documentary, Lily hugged Pc Daley as they met for the first time since she saved her.

Lily's mum Lauren Thorpe said she dreaded to think what would have happened without the police officer's help.

She broke down in tears as she told Pc Daley: "We're just really grateful because without you... it could have been a completely different situation.

"I know you just say you were just doing your job, but we just don't know how to say thank you enough."

Pc Daley comforted the emotional mum, saying: "You've said it, you don't need to say anymore...just seeing you guys here today is all the thanks I need honestly".

The reunion between Lily and her mother and Pc Daley features as part of ITV documentary Manchester: 100 Days After the Attack.

Others featured in the programme are Lucy Jarvis, 17, whose body was hit by more than a dozen pieces of shrapnel.

Lucy was taken to Salford Royal hospital, where surgeons spent 14 hours battling to save her.

The film also features police, paramedics, medical teams, victims and friends and families trying to rebuild their lives after the blast.
