Police have released an image of a Fiat Punto they want to trace as they investigate an arson attack on a family who are famous on video-sharing site TikTok.
The car, which has a noticeable dent on the front-right wheel arch, is believed to be linked to the fire at the southeast London home of the Smithy Family.
The incident happened in Welling on 14 July, with CCTV footage showing two people setting the family's car alight on their drive.
It then spread and caused serious damage to their home. No arrests have been made so far.
The Smithy Family have 3.3 million followers on TikTok and 299 million likes.
Father Nick Smith published a video on Tuesday saying the family had been accused by some of setting the vehicle on fire themselves - which he denied.
"We shouldn't have to be on here to prove our innocence, that shouldn't be the case at all," he said.
"But we are, we're having to do this now, because of these sick, vile people who are twisted enough to think that someone would do that.
"We wouldn't [do that]. Why would I burn my home down after doing all of that work? It annoys me how some very small minded, minority people think.
"We've been to hell and back, and we've done nothing to deserve that."
The family also shared the police appeal on Facebook and wrote: "It's been seven weeks and we are still looking over our shoulders questioning everything and everyone.
"We just want answers so we can move on."
Met Police's Detective Sergeant Danny Banks said: "A team of officers have been working diligently to establish the circumstances of this incident. I thank everyone who has already come forward to the police.
"We are now focusing our investigation on the car pictured and wish to identify it as soon as possible. If you recognise it, please come forward and speak to us.
"No piece of information is too small and could significantly help us in our investigation to establish who is responsible for this attack."
Anyone with any information should call the police on 101 quoting CAD 8350 of July 14.
