The First Additional District and Sessions Judge C. Padmanabhan on Thursday sentenced N. Palanisamy (32) and his brother-in-law S. Karthikeyan (27), who jointly run a power loom unit at Vellanchettipalayam, to life imprisonment for murdering C. Ravichandran, owner of another power loom unit.

M. Sathyanarayanan, the additional public prosecutor, told reporters that the murder took place on August 8, 2011.

The accused had a professional grudge with Ravichandran for taking away some of their labourers to his unit by paying them higher wages. In such circumstances, the accused invited Ravichandran for a social get together in a farm where they beat him to death, Mr. Sathyanarayan said.
