Mr Cameron was a classic car expert and retired from Rolls-Royce in 2013.

This was after working at the company for 20 years, where I had worked on the design of cars such as the 3 Series, Z8, Phantom and Ghost.

Police called it a “violent crime” and said the attacker fled the home on foot.

Search teams are using dogs and a helicopter to track him down.

But an officer told The Sun it is “extremely rare” for a burglar who prepares to disable CCTV cameras to then “stab and kill” someone.

The suspect is said to be between 180 and 190 cm tall, wearing light-colored pants and a dark blue hoodie, carrying a red backpack and yellow-green gloves.
