A 36-year-old man was found hacked to death in his house at MaraimalaiNagar in Nagapattinam on Saturday. The killing is suspected to have taken place in the evening. Arivazhagan, a road worker with the highways department was found in a pool of blood, partly frozen, by his wife and two daughters around 6.30 p.m, when they returned home.

The scene was also partly wiped off blood, in a bid to eliminate traces of evidence. Motive is yet to be ascertained, and hand of known persons is not ruled out. A sniffer dog was engaged at the crime scene.
