There's not much else that the thief could do, in this situation. Aizawa simply had him outclassed. The thief, already straining for air, is unconscious before the Science Police have exited their vehicle.

The entire thing was over almost embarrassingly quick, from the Science Police's perspectives. Still, no one gave him so much as a dirty look as they processed the thief. One of them even offered him a helping hand up when they got close enough. "Thanks for the help, Legionnaire. That could have been messy without your assistance."
