Haridwar, July 21 -- A female elephant and her calf on Saturday night overturned two tractor-trolleys of Kanwariyas on the Doiwala-Dehradun highway after they allegedly got disturbed by loud music being played on their vehicles, a forest official said on Sunday. The incident took place at a Kanwariya camp set up near Manimai temple which is adjacent to NH-72, approximately 200 metres from the Lachhiwala Toll Plaza, an area surrounded by dense forest on both sides. Lachhiwala Range Officer Medhavi Kriti said, "The elephant likely came near the highway in search of food and was provoked to attack Kanwariya vehicles as it got agitated due to loud music and bright lights. We urge pilgrims not to camp near forest stretches or provoke animals with loud music or lights. We've stepped up patrolling in the vulnerable sections, where such sightings have been reported earlier as well." According to the locals, the kanwariyas, instead of keeping a safe distance, flashed mobile lights, recording videos, and even shouting to increase the volume of the DJs mounted on their vehicles. "In the chaos, a kanwariya got injured as people fell over each other trying to escape from the overturned trolleys," said Arun Singh, a local who witnessed the incident. Soon after the forest and police control rooms were alerted, teams from Doiwala police station and the forest department reached the site to secure the area and prevent further escalation, Kriti said. The Doiwala-Lachhiwala highway corridor lies within an established route used by elephants and other wild animals. "The expansion of this highway into a four-lane road has increased traffic movement and disrupted traditional elephant movement corridors. Loud music, flashing lights, and crowding provoke a defensive response from these animals," said Gagan Matta, assistant professor, Department of Environmental Science, Gurukul Kangri University. He added, "Elephants typically avoid confrontation and silently pass through human areas unless they feel threatened. Provocative actions can trigger them to attack in self-defence." In a separate incident in Shivalik Nagar, just 10 km from Haridwar near the SIDCUL industrial area, an elephant was seen wandering through a residential colony. According to local, the elephant had damaged the boundary wall of a community centre and roamed in the locality for about 10 minutes, causing panic among people. "As soon as the control room received the alert, a forest team was dispatched. The elephant was eventually driven back into the jungle. We have increased vigilance in the area and are reviewing CCTV footage to track animal movement," said forest post in-charge Inder Singh....
