Four persons, including a woman, have been narrested in connection with a triple murder in Ashok Nagar in November 2008. The victims were a former senior official of TAMIN, his wife and a domestic help.

Some jewellery and foreign currency were seized from the accused persons, police sources said.

On instructions from Commissioner of Police T. Rajendran, a special team investigating the case made enquiries with cab drivers hired by the retired official Saravanan (74).

Days after he was grilled by police, one of the drivers, Satish Kumar of Villupuram, allegedly committed suicide in his friend's house at MGR Nagar here. This strengthened the suspicion of investigators on the complicity of Satish in the case, the sources said.

“Though Saravanan owned two cars, he used to hire drivers from a travel agency near his house.

When police made enquiries about the drivers who frequently drove for him, it came to light that Satish had got friendly with the family. Knowing that police were tracking his movements, he committed suicide,” Mr. Rajendran said.

On further investigation, police arrested Yasin alias Mohammed Yasin of Adambakkam and Udaya alias Udayakumar of Ashok Nagar. The accused confessed to having conspired with Satish to commit the offence as they had knowledge about the huge quantity of jewellery and cash in Saravanan's house.

On the night of November 18, 2008, the three waited near the house of Saravanan on the first floor of a building in Natesan Salai. When he came home, domestic help Anbarasi went down to open the gate. The accused went inside the house and hid at a convenient place.

Soon after Saravanan entered the house, the accused attacked him. His wife Kasthuri (70) and Anbarasi (17) were also assaulted with lethal weapons. The victims died on the spot. Then the three decamped with valuables, including some foreign currency.

The accused gave a major portion of the booty to Mohandas and his wife Sathyabama of Porur for safe custody, the sources said.

All the four accused were arrested and remanded to judicial custody.

Saravanan's relatives identified the jewellery and cash recovered from them as those belonging to the victim, the sources added.
