Ramanagara (Karnataka), July 13 : Three persons, including a father and son, were killed on the spot and another was in critical condition following a car crash on Sunday in Ramanagara district of Karnataka.

The incident occurred when the car rammed into a retaining wall on the Mysuru-Bengaluru Expressway near Jayapura Gate in Ramanagara taluk in the morning.

The deceased have been identified as 56-year-old Tammanna Gowda, a resident of Chikkanaayakanahalli; his 28-year-old son, Mutturaj; and 27-year-old Sachin, a resident of Hassan. Sanju, who was seriously injured in the accident, has been admitted to a hospital.

All of them were returning to Bengaluru after attending a function at Maduvinakodi village. Ramanagara traffic police rushed to the spot and have taken up the investigation. The police are yet to ascertain the cause of the incident.

According to preliminary investigations, the Swift car met with an accident after the driver dozed off and rammed into the retaining wall on the highway.

The impact of the collision was so severe that the car was completely mangled, according to police.

More details are yet to emerge.

On July 1, four people were killed on the spot and others injured in a road accident reported from the Chikkaballapura district. The incident occurred on the state highway near Makali, close to Doddaballapur town. The deceased were identified as Kalappa, Purushottama, Narayanappa, and Eshwarappa -- all residents of Karenahalli in Doddaballapur.

In an attempt to avoid a head-on collision with the bus and the truck, the driver lost control of the car.
