Commuters walk on railway tracks as services slowly resume in Mumbai on August 30, 2017, after heavy rains.

:: A rush hour stampede during a sudden monsoon downpour at a railway-station in India’s financial hub of Mumbai killed at least 22 people and wounded more than 30, an Indian state official said on Friday.

The cause of the stampede on a bridge at the city’s central Elphinstone station during the rainstorm was being investigated, a police official at the accident site said.

“Two of the injured are in serious condition,” said Deepak Sawant, the health minister of the western state of Maharashtra surrounding Mumbai, who provided the estimate of casualties.

The stampede took place after the cloudburst caught commuters off guard, prompting scores to scurry for cover under the roof of the station’s pedestrian overbridge, said Akash Koteja, one of the injured.

Station’s entry and exit

“Trains were rolling in and some people wanted to get out of the station, but others were not making way. When a few tried, it led to a stampede,” said Koteja.

The bridge is usually crowded at that time of day, as it also serves as an exit route for passengers getting off trains at an adjoining railway-station, he added.

Manish Mishra, a witness who helped some of the injured, said the situation was worsened as police and emergency officials did not respond immediately or enforce crowd control measures.

Police and emergency officials were not immediately reachable for comment on Mishra’s statement.
