Excerpts from Books and Wikipedia
"At this display of Assyrian weakness, the Elamites (who had never really ceased to be a threat) began to prod at the eastern border of Assyrian land. They came as far in as Nippur, and knocked the Assyrian-appointed king of that city off his throne two separate times. They also invaded Babylon with enough force to march through the streets, ascend the temple steps, and nab the statue of Marduk (again), which they took off to Susa in victory. (They also took Hammurabi’s law stele, which remained at Susa until it was uncovered by archaeologists a couple of millennia later.) They kidnapped Babylon’s king, as an afterthought, and took him as well. He was less important than either Marduk’s statue or Hammurabi’s laws, and disappears from the historical record at once."
