He is claimed to have cooked for the 45-year-old married man on Friday night before overpowering him, tying him to a chair and burning his genitals with heated tongs, say police.
The furious father, 36, is then accused of strangling the man to death in a murder plot which had been planned since his 14-year-old daughter was sexually abused two months ago.
The incident took place in Northeast Delhi’s Khajuri Khas area.
After the murder he walked into a police station and confessed to the killing – giving a gruesome account of how he tortured the man.
He said he did not approach the police out of fear that neighbours and relatives would blame his daughter for the incident.
A police spokesperson said: ‘Based on his statement, we sent a team to the spot and recovered the body. It has been sent for a post-mortem examination and his family has been informed. A case of murder has been registered and the 36-year-old man was arrested.’
