A roller coaster at Sunway Lagoon theme park in Subang Jaya abruptly stopped about 200 meters from the launch area on the night of August 22 at around 9 pm, injuring 10 passengers [1, 2, 3, 4]. The ride carried 22 passengers, including both local visitors and foreign tourists, when the incident occurred [1, 2, 3, 4].
The theme park's emergency braking system automatically engaged when the roller coaster halted suddenly, preventing further movement [3]. None of the injured were reported to have died following the event, with patients seeking treatment at various medical facilities in Subang Jaya and nearby areas [1, 2, 4].
Sunway Group founder Tan Sri Jeffrey Cheah suggested the cause may be metal fatigue, though police have ruled out foul play [3]. The roller coaster had been temporarily closed two to three weeks before the incident for inspection and maintenance [3].
The Selangor Department of Occupational Safety and Health (DOSH) issued a prohibition order at the scene and is conducting further investigations. Technical inspections are now underway by DOSH Putrajaya’s Forensic Engineering Division to determine the precise cause of the malfunction [3].
Selangor Menteri Besar Datuk Seri Amirudin Shari said the state government is awaiting a technical report from the police and will conduct a thorough investigation. He said, "I am waiting for a technical report from the police and they will conduct a thorough investigation into the incident because it has been taken up as a duty for the police to take action" [1, 2, 4].
Officials continue to investigate the safety protocols and mechanical status of the ride following the incident on August 22.
