A PROLIFIC thief who stole £100,000 worth of valuables from magician Dynamo's London home while he was away on holiday is facing years behind bars.

Alistair McWilliams, 33, broke into the £1.3million Grade II listed home near Hampstead Heath and made off with Rolex and Cartier watches, jewellery, an iPad and a laptop.

The thief also stole a deck of cards belonging to the magician and left possessions strewn around the bedroom floor.

He broke into the North London house on May 20 by propping a ladder up against the adjoining fence and jumped over, before smashing a rear door and ransacking the master bedroom.

McWilliams triggered an alarm at the home Dynamo - real name Steven Frayne - shares with his wife Kelly.

But it was dismissed as a false alarm when a friend went round to check the front of the property and could see nothing wrong.

James Dawson, prosecuting, said when the magician and his wife returned home from their holiday they "initially didn't think there had been a burglary because the ground floor was untouched".

But he added: "When they went to the bedroom, they immediately realised they had been burgled.

"Property was strewn over the toilet area, there had been a rough search."

McWilliams was caught thanks to DNA he left behind on a tree branch while clambering over the fence.

He then spun a web of lies, bizarrely claiming he'd been hiding from men he had stopped having sex on the Heath.

Judge Brendan Finucane warned McWilliams he faced a lengthy jail term when he's sentenced on Wednesday.

He said McWilliams had a "horrible" criminal record including burglaries, thefts and a £200,000 raid on a jewellers in Exeter, Devon.

He was jailed for nine years in 2013 for his role in the smash and grab at a branch of Ernest Jones in Exeter.

Last year Dynamo, 36, spoke out about his secret battle with Crohn's disease which put his career on hold.

The illusionist revealed he was diagnosed with the disease, a type of inflammatory bowel, as a teenager.

He was forced to have half his stomach removed when he was 17.

Last March he shocked fans by sharing an image of himself with a bloated face, showing the side effects of his treatments.

He also admitted he was in "excruciating pain" nearly every day, and had banned gluten, diary, fat and vegetables from his diet.

McWilliams is already facing jail for a horrific hit-and-run in Kentish Town that took place just three months after the raid.

He admitted causing death by dangerous driving after ploughing into 77-year-old great-granddad Richard Dougherty on August 23.

McWilliams fled on foot instead of going to Mr Dougherty’s aid, abandoning the wrecked car as it leaked fuel and was at risk of bursting into flames.

Mr Dougherty was taken to hospital with severe head injuries but died 11 days later.

Police issued an appeal to catch McWilliams after the smash, describing him a “very dangerous and selfish man”.

He was finally captured in September and was charged with both the burglary and causing death by dangerous driving.

He will be sentenced for both crimes on Wednesday.
