Police in London are searching for a burglar who stole over £10.5 million ($13.2 million) worth of jewelry, handbags, and cash from a mansion near Regent’s Park on December 7.

The armed intruder entered through a second-floor window while the owners—an Instagram influencer and her developer husband—were away.

Surveillance footage shows the burglar narrowly avoiding a housekeeper.

Stolen items include a 10.73-carat diamond ring and £150,000 ($189,000) in designer handbags, the Associated Press has reported.

The homeowners are offering a £500,000 ($628,000) reward for information leading to an arrest and conviction, plus 10% of any recovered valuables.
