Jewellery worth more than £10m as well as designer handbags worth £150,000 have been stolen from a house in St John's Wood in London.
A white man aged in his late 20s to 30s had broken into a house in Avenue Road between 17:00 and 17:30 GMT on 7 December by climbing in through a second-floor window, the Metropolitan Police said.
He took the Hermes Crocodile Kelly handbags, £15,000 in cash as well as items of jewellery worth £10.4m that included unique pieces.
The homeowners have offered a £500,000 reward for information that leads to the arrest and conviction of the suspect.
