The news of Krishna's exploits were constantly pouring in Kans's court and he looked his death getting more and more imminent. So, he chalked out another plan to put an end to Krishna's life.
Kans had a demon, named Arishta, in his service. He was now entrusted with the job of eliminating Krishna. So, Arishta got to Vrindavan and began to create trouble there. He wanted that his activities should force Krishna for an encounter so that he might get a chance to kill him. Arishta transformed himself into a violent bull and damaged many a house with his horns. He uprooted several trees and killed a number of cows and calves too. Getting the news of Arishtasur's intolerable activities, Krishna decided to punish him.
Krishna, accompanied by his brother, went to where the demon was creating trouble. He challenged him with a clap of hands. Balram, when he saw the furious bull, asked Krishna not to face him but Krishna paid no heed to his advice. Arishtasur, mad in rage to hear the challenge, rushed at Krishna who caught hold of his horns and pushed him back to a distance and then threw him on the ground with a violent jerk. Giving him no chance to rise again, Krishna twisted his neck with such a force that he fell down dead with a thud.
