It's been a pretty heist-filled holiday season in New York! First, the $1 million art heist; then on Christmas day, three masked men stole $879,000 worth of jewels from a diamond store, escaping by jumping roof-to-roof.

Here's some security camera footage of the three thieves after they sneaked into Ultra Diamonds on West 23rd Street from the roof, via the Post:

Some are speculating it was an inside job, since the rooftop door the thieves entered the building through was suspiciously left unlocked. Another suspicious fact: The heist took place just one day before the entire city was buried under a massive snowstorm, thus hampering any investigation. Do these thieves control the weather!?
