Lucknow, Dec 27 (IANS): In an apparent case of honour killing, a 27-year-old man allegedly killed his sister for having an affair with a man and buried her body inside the house in village Parli under the Sairpur police station on the city outskirts.

The police took cognizance of the crime themselves and lodged an FIR as no villager or relative lodged a written complaint with the police against the accused.
