Wild video shows the alleged knife-wielding Central Park rapist ask cops “what happened, man?” as he’s arrested while working at a Burger King in Miami.

Officers with the NYPD and US Marshals Service are seen drawing guns on Dereck Rivera-Deleon, 30, yelling “On your face now!” as the creep takes a break outside the fast-food chain, bodycam footage shows.

Rivera-Deleon is then seen moving to the ground with his hands behind his back, but not before asking officers “what happened, man?” according to the video.

As cops say that they’re going to take his bookbag off, Rivera-Deleon starts to protest.

“Why the bookbag? What happened, man?” he’s seen asking in the video, before cops pat him down and take him away.

Police said the sicko allegedly flashed a knife, dragged the victim into the desolate area near East 67th Street and Fifth Avenue around 8:30 p.m. Oct. 26, and sexually assaulted her.

The woman was hospitalized in stable condition, according to authorities.
