"On Monday the Indian worker, who has been identified as HUM committed suicide on the track," said Major General Khamis Mattar Al Mazeina, Deputy Chief of Dubai Police.
"The speeding Metro struck the man while he was lying on the track. Man was under the influence of alcohol and used the emergency fire exit to access the track," he said.
Mazeina said HUM was working in Dubai since 2010 and had asked his company to cancel his residency visa and send him back home.
The deceased's body was beyond recognition and police took two days to identify him after one of his friends filed a missing report about him.
