CCTV has captured the moment a "Molotov cocktail" was hurled at the Chelsea home of socialite Petra Ecclestone.
The incendiary device is seen flying over a driveway gate before bursting into flames next to the owner’s Range Rover.
The arson attack happened in Old Church Street on April 24, while the owners of the property were out.
The Metropolitan Police has not named the victim but it is believed the multi-million pound property belonged to Ms Ecclestone, daughter of the Formula 1 racing supremo Bernie Ecclestone.
Police were called at around 5.25pm to reports of a fire on a driveway. It was quickly put out by firefighters, and police called to the scene found a smashed bottle.
As well as capturing the moment a bottle of flammable liquid was thrown, CCTV also captured two men police are keen to speak to, who were seen running past the address at the time of the incident.
They are both black and wearing dark clothing.
Detective Constable Clare Reynolds, of Kensington and Chelsea CID, said: “We are keen to hear from anyone who may recognise those shown in the images released, or anyone who witnessed the incident.”
There have been no arrests.
Anyone who can help with the investigation can contact Kensington and Chelsea CID via 101 or email Gangs@met.police.uk
