Ariana Grande Manchester concert attack: Heartbreaking final text of bomb victim Olivia Campbell

A teenager killed in the Manchester terror attack sent a final text to her boyfriend just 30 minutes before she was killed.

The 15-year-old told her boyfriend Lewis Brierley that she was "having so much fun" at 9.53pm - the last message she sent before she was killed in the nail bomb massacre, reports The Sun.

He shared the heartbreaking photograph of their last text exchange as he paid tribute to his girlfriend - and vowed to "never forget her as long as I live".

It comes just hours after the teenager's devastated mum broke down at a vigil held for the bombing victims.

Charlotte Campbell had to be supported by the teenager's stepdad Paul Hodgson as she wept over the death of her daughter.
