NAVI MUMBAI, July 4 -- A 20-year-old student from Pune drowned in the sea in Kashid on July 1, and the police recovered his body only 43 hours later in a search operation which included the use of thermal drones and helicopters to scan the area. The deceased, Tanishk Malhotra, had come to Kashid on a day trip with his friends, Mark Milton, Varun Tiwari, and Punya Patil, all final-year undergraduate students from Pune. The group got into the sea for a swim but misjudged the depth of the water, the strength of the waves and the current. Their swim took a tragic turn when only three of them managed to return safely to the shore and Malhotra, pulled into the sea by the current, went missing. Rescue efforts were launched immediately by the Murud Police, Coast Guard, local lifeguards, the Sahyadri Vanyajiv Rakshanartha Samajik Sanstha (SVRSS), a wildlife and disaster rescue organization, and other emergency services. "Due to strong current the deceased's body remained untraceable," said the police, adding that they then began an aerial search with the Indian Coast Guard's helicopter. On July 3, advanced thermal drones were deployed along with the helicopter and Malhotra's body was located around 7:45 am. The body was sent to Murud Rural Hospital for post mortem and further procedures....
