There was a heartwarming father-daughter moment as one 49-year-old dad took a photo with his 14-year-old daughter.

“What an incredible night!” he posted on social media.

Helen Baxter took a selfie with her 13-year-old daughter, Katy, and her child’s best friend. The concert tickets had been given to the children last Christmas.

Joe Nuttorn took a selfie with his daughters as thousands of other excited Grande fans filled the arena.

Moments later all those smiles would turn to horror as 22-year-old suicide bomber Salman Abedi waited for the concert to end as he unleashed carnage outside the arena, killing 22 and injuring 59.

Among the victims is 18-year-old Georgina Callander, who met Grande at a concert two years ago and treasured a photo of their meeting.

Before the concert she had tweeted her idol: “So excited to see you.”

The youngest victim was only 8 years old, Saffie Rousos, was still in elementary school.
