BBC reporter Robert Peston has pleaded with thieves to return jewellery belonging to his dead wife.
Burglars ransacked the Muswell Hill home of BBC Business Editor Peston on Wednesday, stealing engagement, wedding and cariad rings.
Peston, 52, who became a household name for his reporting on the 2008 global banking crash, used Twitter to call for the return of the items.
Wife Sian Busby died from lung cancer in September, after a five-year battle against the disease.
"The loss of my wife's engagement, wedding and cariad rings is desperately upsetting for me and our two sons," wrote Peston.
"I had hoped to pass them on to the boys. If anyone knows anything about their whereabouts, I would be so grateful."
Thieves forced their way into the property via the back door and then ransacked Peston's home. Two laptops with potentially sensitive material were also stolen, along with an iPad.
A Scotland Yard spokesman said: "Anyone with information about the burglary or the rings is asked to call police on 101. Alternatively call Crimestoppers anonymously on 0800 555 111."
