In my opinion, it is more likely that a deal was cut with her to flee the country and the military was bribed or otherwise brought on the side of the soon-to-be PM. The larger point is that the overturning was NOT a people's lead revolution. This was implemented behind the public's eye.
"The Duran" channel recently covered this and came to the same conclusion, i.e. that this was in fact a Western-backed coup related to access to the Bay of Bengal.
To clarify: her home was stormed, but not until after she had fled.
