As soon as the figures run from him, Prometheus gives chase. He doesn't bother shouting, "Stop!" or "Hold it right there!" For one, he knows that they won't listen, and for another, he'd rather not give away his position in case any more of their red-clothed buddies are lying in wait elsewhere.

Of course, a group of people running is bound to make some noise. The nice thing about alleyways is that there aren't many directions to run off to. At least not horizontal ones. These characters seem human to the Titan, so he's not terribly concerned about them suddenly taking flight or slithering up the wall. All the same, he holds his spear out, jabbing at them like a farmer might do with a cattle prod, herding the lot of them around the corner and hopefully into Daredevil's vicinity.

One thing of note is that he is not as vicious with those stabs as he could be. He's not trying to impale them, simply corral them.
