The Adventures of Robin Hood...chapter 7

Robin Hood was not arrested because he killed Gisborne in a sword fight.

Then Robin Hood wiped his sword and thrust it back into the scabbard, and, coming to where Guy of Gisbourne lay, he stood over him with folded arms, talking to himself the while. "This is the first man I have slain since I shot the Kings forester in the hot days of my youth. I ofttimes think bitterly, even yet, of that first life I took, but of this I am as glad as though I had slain a wild boar that laid waste a fair country. Since the Sheriff of Nottingham hath sent such a one as this against me, I will put on the fellow's garb and go forth to see whether I may not find his worship, and perchance pay him back some of the debt I owe him upon this score."
