The police have appealed for witnesses and asked anyone with dashcam footage to get in touch.

"I just saw the first few - my jaw totally dropped. I just thought this was some of the most extraordinary work I'd seen," he said.He was determined to have one for himself, so made an impulse purchase - one he said he does not regret at all.

"The skill level is amongst the best artistry I've seen," he said.For the untrained eye, the first thing you might notice about Orlik's work is how precise it all is. Some of it feels quite science-fiction.Mr Ford explained that Orlik has always had a strong interest in physics, and it shows.

He uses tiny squiggles on the paintings that make up the colours, which he calls "excitations”.Friend Mr Pietruska said to create the effect, Orlik would sometimes use just a couple of hairs on a paintbrush at a time on each one, which could take huge amounts of time.

First training at the Swindon College of Art as a contemporary of Gilbert O'Sullivan and Virgin Atlantic logo designer Ken White, Orlik also went to Cheltenham School of Art.

Mr Pietruska is glad his friend is finally getting recognition.Cai says he has noticed that videos with millions of likes can be persuasive to other young men his age.

For example, he says one of his friends became drawn into content from a controversial influencer - and started to adopt misogynistic views.His friend “took it too far”, Cai says. “He started saying things about women. It’s like you have to give your friend a reality check.”

Cai says he has commented on posts to say that he doesn’t like them, and when he has accidentally liked videos, he has tried to undo it, hoping it will reset the algorithms. But he says he has ended up with more videos taking over his feeds.So, how do TikTok’s algorithms actually work?
