This is the moment one of Britain's worst rogue traders was arrested after defrauding his customers out of more than £1.25 million.
Mark Killick, who was known to his customers as Marc Cole, spent his customers' money on travelling the world in style as well as funding his own gambling habit.
Between 2019 and 2021, more than 100 complaints were made against him.
He was charged with 46 counts of fraud by false representation and found guilty of 37 of those counts.
It is estimated that the value of the work which had not been completed across the victims was about £1,270,000, the equivalent of a 'lottery win'.
Footage captured the moment the serial fraudster was finally caught by police and detained.
Killick, from Paulton, Somerset was found guilty after a 14-week trial and is due to be sentenced on Monday, December 22. He was remanded in custody until then.
Speaking after the case, police described Killick's offending as 'fraud on an eye-watering scale.'

The trial heard how Killick would request customers pay large sums of money upfront to enable him to pay for orders or materials.
He then stressed to some customers they needed to pay their bills 'urgently' - but the court was told he was running a 'ponzi scheme' and effectively using that money to fund the work for customers who had paid him months before for jobs he had not completed.
He was also accused of failing to pay suppliers and contractors too - further increasing the company's liabilities.
Killick's company, TD Cole Ltd, began work for some of his customers, who would then see no progress for weeks or months at a time, having already spent tens of thousands of pounds.
The prosecution said the victims were in a weak bargaining position, because their house had been turned into a building site and they were left waiting for Killick to return calls and messages to explain when work would re-start.
Therefore, if he asked for more money, they felt compelled to pay to avoid writing off their financial losses.
Other customers paid Killick and TD Cole for work that was never even started.
The jury retired to consider their verdicts over several weeks and found Killick guilty of 37 counts of fraud by false representation (33 unanimously and four by majority verdict) and not guilty on one count. The remaining eight counts he was not convicted of.

Speaking after the guilty verdict, Detective Sergeant Louise Sinclair said: 'Mark Killick sold his customers a housing redevelopment dream.
'He left them with a nightmare and thousands of pounds out of pocket.
'It was fraud on an eye-watering scale.
'The change of name prevented any of Killick's customers who researched his credentials from seeing the media reports of his previous fraud convictions.
'He is a serial fraudster.'
Killick's name change had hidden his previous criminal record which included being investigated and prosecuted twice for fraud offences relating to failing to complete building work after asking for deposits between 2008 and 2014.
His victims were also unaware of the financial issues TD Cole Ltd was facing.
In 2008 he was convicted under the name Killick and in 2014 under the name Mark Jenkins, which was his grandfather's name.
In the 2000s he was also declared bankrupt.

In January 2019, Killick changed his name by deed poll to Marc Cole and the following month created TD Cole Ltd - he told the jury this name change was for family reasons.
Killick, when later questioned by police, said the business started well with customers sharing positive online reviews.
He claimed events outside of his control hugely impacted on how quickly jobs were able to progress, including Covid-19, fuel strikes and a collision he was involved in.
Killick, which is his birth name, was investigated by Trading Standards in 2020, following a series of complaints about the business.
The investigation was subsequently referred to Avon and Somerset Police, who worked alongside the Crown Prosecution Service, to secure the 46 charges.
Killick chose to liquidate TD Cole Ltd at the start of November 2021 after building up liabilities he could not afford, but was continuing to take customers' money in the days before.
He was arrested by detectives a few weeks later.
He told police during interviews he was starting a new company called Cole Design, which would be a sole trader, and that this business would have finished any unfinished TD Cole Ltd work.
He said his arrest prevented that from happening.
Victims were unaware of Killick's past convictions and were not aware of his company's financial troubles
DS Sinclair added: 'Lots of companies took a big financial hit because of the Covid-19 restrictions.
'Lockdowns and self-isolation meant it was a really difficult environment for businesses and the struggles Killick faced were replicated across the country.
'Had he explained to customers Covid-19 was impacting on when the work could be started, I've no doubt most, if not all, would have understood that.
'But that's not what he chose to do, because he wanted their money.
'He chose to lie time and time again, putting pressure on customers to hand over large sums of cash to secure orders for them, when he knew the money they were giving was not going to be used for their work at all.
'Killick was paying himself a commission for every job secured, and therefore some of the cash customers were handing over expecting to be paying for their construction projects and orders, was instead going to his personal account and being used on hotel stays and gambling.
'The perilous financial situation was such that Killick was using a pawnbrokers for cashflow, unbeknown to his victims, and he was continuing to ask for payments a few days before liquidating TD Cole Ltd.
'Killick's claim he would have completed the work through a new company does not bear up to scrutiny when you consider the lies he had already spun to customers and the fact the money he'd been paid for those jobs had already been spent. He did not have the funds to do that.'
Speaking after the case, Martyn Nicklin, Trading Standards Investigator at Bristol City Council, said: 'The conclusion of this trial is also an opportunity for us to remind anyone considering building works to do their research to make sure they are employing a trader that is competent and responsible.
'There are many excellent tradespeople out there, but there are also a significant number of rogue traders that offer what sounds like an excellent service and price but will be unable to deliver either on time or on budget.'
