I've seen the same phenomena in dozens of ancient temples in India I had the chance to visit, often attributed to Islamic conquests. The native Hindu rulers weren't any less sparing either when they conquered their rivals who worshipped a different deity.
Hindu rulers tended not to do these kinds of specific acts. You could probably count on one hand the "Indic" kings documented to have specifically targeted temples or religious iconography. The most famous examples that come to mind immediately would be the razing of the temples of Pratihaspura, allegedly to smoke out a rival hiding in the ruins.
