Hello alan,
There are only six suttas mentioned in the link I gave - not sure if any fit exactly.
I can't find the actual sutta you are refering to - but this one shows that arahants still experience kamma from previous actions:
From the Suttas:
MN 86 Angulimala Sutta: About Angulimala Then Ven. Angulimala, dwelling alone, secluded, heedful, ardent, & resolute, in no long time reached & remained in the supreme goal of the holy life for which clansmen rightly go forth from home into homelessness, knowing & realizing it for himself in the here & now. He knew: "Birth is ended, the holy life fulfilled, the task done. There is nothing further for the sake of this world."
And thus Ven. Angulimala became another one of the arahants.
Then Ven. Angulimala, early in the morning, having put on his robes and carrying his outer robe & bowl, went into Savatthi for alms. Now at that time a clod thrown by one person hit Ven. Angulimala on the body, a stone thrown by another person hit him on the body, and a potsherd thrown by still another person hit him on the body. So Ven. Angulimala — his head broken open and dripping with blood, his bowl broken, and his outer robe ripped to shreds — went to the Blessed One. The Blessed One saw him coming from afar and on seeing him said to him:
"Bear with it, brahman! Bear with it! The fruit of the kamma that would have burned you in hell for many years, many hundreds of years, many thousands of years, you are now experiencing in the here-&-now!" [3]http://www.accesstoinsight.org/tipitaka ... .than.html with metta
