Actor Archie Lyndhurst died from a brain haemorrhage, his mother Lucy has revealed.

The 19-year-old CBBC star was found dead at his family’s home in West London.

In a frank and honest post on Instagram Lucy said:

“Dearest friends, it’s so difficult to know where to start.

“There is no easy way in any of this.

“On the 22nd September our world blew apart, the damage caused to it totally irreparable.

“Archie was, and always will remain our everything.

“Those of you who know us know the catastrophic effect it has had and will have on us for the rest of our days.

“Archie was the most extraordinary magical human being we have ever met. We are still learning each day the incredible impact he had on others’ lives, the kindness and generosity he showed them.

“He was an old soul and incredibly advanced for his years in many ways.

“As his parents we couldn’t be prouder of him for all he achieved in the short time he was given, and especially for the beautiful human being he was.

“We are so grateful and privileged to have been chosen to be his parents.

“The journey and adventure have been the best anyone could ever have wished for.

“A truly magical time in every way possible.”

Lucy and her husband Nicholas Lyndhurst – from Only Fools and Horses – discovered the cause of Archie’s last month.

She said:

“Four days before Christmas Nick and I sat in Harley Street with the results of Archie’s second post-mortem.

“A very detailed document, which we had been warned by the coroner would be a harrowing read, and best explained by a medical practitioner.

“The Dr explained Archie died from natural causes (something we knew already, only gossips, keyboard warriors, trolls and the ignorant thought differently)

“He died from an Intracerebral Haemorrhage caused by Acute Lymphoblastic Lymphoma/Leukaemia.

“This is not Leukaemia as we know it, the word Acute in medical terms means rapid.

“He assured us that there wasn’t anything anyone could have done as Archie showed no signs of illness.”

Lucy continued:

“Archie had numerous bleeds on the brain and the Dr went to great lengths to reassure us that he wouldn’t have been in any pain as it happened in his sleep.

“The results utterly floored us to think something like this could happen.

“It’s very rare and around only 800 people a year die from it.

“Only days before he’d been with the love of his life Nethra celebrating his birthday early as she was due to go away with work commitments.

Life is fragile, precious and sometimes incredibly cruel.”

A coroner’s inquest into the cause of death has now been dropped.
