What happened to Nomu when he fought All Might (My Hero Academia)

The Nomu started to beat him, but then Allmight was told he had shock absorbtion and this made Allmight realize there had to be a limit to the absorption. So Allmight released a lot punches on him, and Nomu's shock limit was full. This was when Nomu blasted through the top of the USJ. He was later found by police and they tried to question him.
