A demolition site near JR Chiba Station turned into a scene of chaos Thursday morning when a ceiling collapsed, sending rubble crashing down and trapping three workers, according to media reports.

Two men, a man in his 70s and another in his 50s, were trapped under the wreckage. The man in his 70s was rescued and transported to a hospital, but he was later confirmed dead about four hours after the rescue, NHK reported. The man in his 50s was rescued approximately five and a half hours later but was pronounced dead at the scene. Additionally, a man in his 30s, who was also on the truck bed, sustained a minor neck injury.

The incident occurred around 10 a.m. in the Fujimi area of Chuo Ward in the city of Chiba. According to the fire department, the collapse caused debris to fall from the second floor to the ground, trapping the workers.

The site, located in an office district approximately 200 meters east of Chiba Station, was handling demolition work on a former city cultural plaza.
