$1.2m raised for teen after legs amputated in crash

The public has raised over NZ$1.2 million for an up-and-coming teenage motorsport driver whose legs needed to be amputated after a horror crash.

British racing driver Billy Monger, 17, was involved in "one of the most horrific crashes motorsport has seen", his family says.

Footage from an in-car camera shows his car smashing into the back of another during a British F4 race at Donington Park on Sunday last week (local time).

Monger was trapped in his car for an hour-and-a-half before being taken to hospital, where he's in a "critical, but stable condition," F4 officials say.

"Due to the injuries sustained and despite every effort, Billy has sadly had both lower legs amputated," they said in a statement.

"He has been kept in an induced coma while undergoing surgery, from which he is expected to be woken in the next few days."

Monger's family are appealing for help to support the teen - and 17,067 supporters have done just that, donating over NZ$1.27 million.

"Help Billy Monger beat life changing injuries, after being involved in one of the most horrific crashes Motorsport has seen," his family say on their JustGiving page.

"Thousands of people have already watched the haunting footage of the crash which left Billy fighting for his life.

"We now need your kindness and support to help give Billy and his family the best chance to fight these injuries that will affect Billy's life so massively."
