Twenty people, including women and children, were left stranded 75 feet above the ground after an amusement ride malfunctioned at an exhibition held at Codissia Grounds in Tamil Nadu’s Coimbatore. The incident occurred on Tuesday night when around 20 visitors, including three children, were stuck on the ride, prompting police and the Fire and Rescue Department to respond. Using a sky lift vehicle, the rescue team worked for roughly 45 minutes to safely bring everyone down. The incident has raised safety concerns, following a similar case in Chennai last year where visitors were left stranded on an amusement ride, highlighting the need for periodic inspections and strict safety checks of such attractions.
