According to law enforcement sources, 3 suspects got into the house through an unlocked window and A$AP's sister walked in on them.
The robbers got away with about $1.5 million in jewelry and other property.
They also took a safe, but left it on the sidewalk for some reason before bolting in their getaway vehicle.
TMZ sources say it looks like this was not a random hit.
A$AP posted a video showing one of his buddies dropping a ton of cash into a bill counter.
