A retired Navy officer and his wife have been shot dead at their house by unidentified gunmen.
Ilangovan (69) and his wife Ramani (62) were killed on Monday evening at their house in Neelankarai off the East Coast Road. The couple's daughter-in-law and two grand children were injured, and are now in hospital.
One of the robbers was caught by neighbours, and handed over to police. His interrogation is expected to lead the police to the others involved in the murder.
