A 5-year-old boy with prosthetic legs has raised $1 million for the NHS by walking 6 miles

Tony Hudgell takes the final few steps of his weeks-long challenge.

London (CNN)A 5-year-old boy with two prosthetic legs has raised more than £1 million ($1.2 million) for the hospital that saved his life when he was just weeks old, by walking a total of six miles over the past month.

Tony Hudgell lost both his legs after suffering abuse from his biological parents as a newborn, which left him on life support at a London children's hospital.
He set out to raise £500 for the same hospital by walking throughout June -- but smashed that target almost instantly, raising £1.1 million on his online fundraising page as of Wednesday.
    Tony completed his walk on Tuesday in front of a sizable crowd in his hometown of West Malling, southeast England, and celebrated with his adoptive family.
