Police said Shiva Basavegowda (29), who was arrested today, hatched the plot to kill the man, a deputy manager in a private bank, after learning that his colleague would be marrying him.
He befriended the man about six months back and on December 3 took him to a hamlet near Kaggalipura, about 30 km from here and electrocuted him, using an electrical line he had earlier drawn from a small transformer.
A case of murder, criminal conspiracy and destroying evidence was registered against him, they said.
