Mumbai, June 2 -- A 20-year-old man drowned on Saturday after he slipped and fell into the sea at the Juhu Koliwada beach jetty while posing for pictures. Despite attempts to save him, he was declared dead at the hospital. The deceased, Anil Rajput, a resident of Koliwada, Khar Danda, had gone to the beach with his roommates, said the police. An eyewitness at the site, Nicky D'Scouza, who runs the community Juhu Buzz, described seeing the four men approach the edge of the jetty at the Juhu Koliwada beach at around 5pm, ignoring the warnings from people around them. "The water was very rough and splashing violently against the rocks," said D'Souza. Rajput was posing on the rocks when at 5:43pm, as per D'Souza, a strong wave struck him and pulled him into the water. As he started shouting, people around called emergency services and lifeguards stationed further away along the beach were informed within minutes. D'Souza said that a bystander jumped into the water to rescue Anil, but he panicked and clung to the rescuer not letting either surface safely. The rescuer had to retreat, and Rajput sank into the water soon after. Two lifeguards reached the spot soon, pulled Rajput's body onto the jetty and attempted CPR, but he did not respond, said D'Souza. He was rushed to the Cooper Hospital but did not survive due to excessive water intake. The Santacruz police have registered a case of accidental death. D'Souza alerted visitors that the waters at Juhu Koliwada were dangerous, and there was a very narrow window to rescue a drowning person....
