A husband and wife were killed and their son injured seriously, when a car collided against their motor cycle near Kittampalayam on the outskirts of the city on Thursday night.

The 50-year old Muthuraj, working in a power loom unit near Karumathampatti, was going home with his wife Poopathi (39) and son Prithviraj (22). Suddenly, a speeding car rammed into the two-wheeler at a junction, throwing the trio on to the road, police said.

Investigations revealed that one Rangasamy, running a power loom unit, was driving the car when the accident occurred and search is on for him.
