An anonymous donation of £15,000 helped tip an Ayrshire boy's cancer appeal beyond its £250,000 target.

The six-figure sum has been raised for four-year-old Calum Rae, who is currently living with stage 4 high risk neuroblastoma - a rare and very aggressive cancer.

The Troon boy requires the money to fund a trip to New York, where he will receive a miracle vaccine being trialled on children.

The drug could prevent the neuroblastoma from returning.

And this week the £250,000 target for the drug was reached.

Mum Victoria MacDonald and dad Andrew Rae launched the appeal in April, after receiving Calum's diagnosis in March.

As the donations got closer to their target, one anonymous donor submitted a single £15,000 donation.

The anonymous donation came with the attached message: "Calum, you are a strongest, bravest and most courageous little boy."
