He witnessed the incident and explained what happened.
The man had missed the train and he started running, even though the doors had closed, he ran towards the centre of 2 carriages where they link together. He apparently tried to jump but missed the joint, landing just short of it. Trapping him between the carriage and the platform.
My brother said that even though the authorities were within meters of the trapped man, they didnt respond. It took them upwards of 15 minutes to respond.
The man tragically suffered because he was still alive and breathing, yet no body responded to his cries for help.
