Two friends who had boarded an interstate bus from Karnataka to Tamil Nadu on Wednesday morning hadn't imagined their journey to unfold in this manner. While one of them died on the bus, reportedly of a cardiac arrest, the other was offloaded on the highway with his friend's body. Radhakrishnan, 45, and 55-year-old Dheeran boarded the bus in Bengaluru. They paid Rs. 300 for two tickets to Thiruvallur in Tamil Nadu. As soon as they settled in their seats, Dheeran dozed off. When a fellow passenger asked Dheeran to sit up, he didn't move. He had stopped breathing.
