The police have arrested three persons for killing T. Srinivasan (39) of Thindal Kargil Street in Erode.

The arrested were: Srinivasan’s wife Lalitha (26), her elder sister Yasodha (29) and her husband Gopalakrishnan (31).

According to a complaint by Srinivasan’s father, a gang of four aged between 20 and 30 years beat his son to death, threw chilly powder on his daughter-in-law’s face and stole 21.5 sovereigns of gold jewellery from the house.

But investigations revealed that it was these three persons who killed Srinivasan.

The police have recovered all the jewellery and a two-wheeler that was used for the murder, from the accused.

Srinivasan reportedly bought properties in the name of his mother and was leading a lavish lifestyle without giving any money to wife.

It infuriated Lalitha and she plotted to kill him, the police said.

After killing him Lalitha asked Yasodha to keep the jewellery safe with her.
