I think someone reported a mysterious package being left there la. Then report police. Or some anonymous tip off saying there is bomb there. But so many CCTV in the premise cannot see who left that package there meh?

Or maybe the guy who left the package there is suspicious looking? Anyway i think they blew it up with a smaller charge dropped by the robot. Last i read that is the payload is small, they will bunk the around the package and probably a probe or robot is used to deliver a controlled charge to detonate the bomb.

If this is a confirmed case today, then expect more cops to be everywhere.
