Alice Pyne, a terminally ill teenager whose online 'bucket list' went viral, has been left devastated after internet trolls posted abusive messages on her site.

The 15-year-old, who has lymphoma cancer, wrote a list of all the things she wanted to do before she dies in her blog, which went global.

However, Alice's mother, Vicky, 42, has revealed "lowlifes" have left sick messages on her website – including one who asked: "Has the bitch died yet?"

She vowed to prosecute "every single one" of the people behind the anonymous messages on Alice's Bucket List.

"With regard to all the not-so-lovely 'anon' comments being left, particularly the one asking if the bitch had died yet, you are only 'anon' on this blog, you are not invincible and you are traceable," she said.

"We will find and prosecute every single one of you. I haven't stood by Alice for four years to be affected by a bunch of … can't say what I'd like to.

"Don't underestimate me … I'm a mother."

Alice's prompted a flood of offers after it became a hit on Twitter.

Her list included meeting Take That – and she went to see the band perform in concert last weekend and got to meet Gary Barlow, Robbie Williams, Jason Orange and Mark Owen.

Mrs Pyne told the Metro: "They were all absolutely lovely. I'll be eternally grateful to them for the smile they've put on my daughter's face."
