The BBC calls the Milan theft a Daring $1m mid-day heist:

Staff at Pederzani’s, one of the city’s exclusive jewellers, thought nothing amiss when a window cleaner went to work on the plate glass display.

Dressed in regulation overalls, he propped his ladder against the window.

But then, instead using the bucket and squeegee to clean it, he calmly unscrewed it before scooping an estimated $1m-worth of jewels into his bucket and walking off into the Friday shopping crowd.

You can unscrew the window from the outside? How do you remove a window that you’ve propped your ladder against? Maybe something was lost in translation.
