Hoshiarpur, Sept. 7 -- Three persons were killed and two injured when an ambulance rolled down a gorge near the Manguwal barrier on the road to Chintpurni in Hoshiarpur district of Punjab on Saturday, police said. The ambulance was carrying a heart patient from Tanda in Kangra district of Himachal Pradesh to Ludhiana when the accident occurred. The patient and his two sons-in-law died in the mishap, while the ambulance driver and a relative of the deceased survived with serious injuries.

Local residents helped the police extricate the bodies and the injured. Sadar police station house officer Madan Singh said that people from nearby areas informed the police when they heard the cries of a woman. "With the help of locals, we pulled the two injured from the 400-ft deep gorge and sent them to the civil hospital. The bodies were extricated later and sent for post-mortem," the SHO said. The deceased were identified as Onkar Chand, the patient, Rakesh Kapoor and Sanjiv Kumar, all residents of Pathiyar village in Kangra's Nagrota Bagwan tehsil.
