An 18-year-old college student died after falling unconscious on a simulated waterfall at Kolkata’s Nicco Park on Wednesday.

He was rushed to a private hospital in Salt Lake, where doctors declared him dead.

According to the amusement park’s authorities, Rahul arrived at around 11 am with a group of friends.

Rajesh Raisinghani, managing director of the park, said they do not consider the death an “accident”, suggesting it may have been due to an underlying illness.

“Our staff suddenly saw some friends trying to bring a boy down (from the waterfall). He was found unconscious. Immediately, a wheelchair was brought in. He was first taken to primary care where the nurse found his pulse low, and suggested we take him to emergency services. By then, we had already called an ambulance. Later, doctors declared him dead. The incident took place this afternoon,” Raisinghani said.

Park officials said that Rahul, along with “four men and three women,” believed to be college students, were taking a shower on the first floor of the Niagara Falls simulation when he suddenly felt dizzy and collapsed.

The Bidhannagar South police have taken charge of the investigation. Authorities are currently interviewing Rahul’s friends to gather more information about the circumstances leading to his collapse. The unexpected death has reportedly caused panic and concern among other tourists visiting NICCO Park.

The cause of death remains uncertain, and an investigation is on.
