Police say a stampede at a Mumbai local train station has seriously injured at least 20 people amid heavy rains in the morning rush hours.

Police said the stampede was triggered by a rumor that a pedestrian overpass collapsed after concrete chunks fell. Chaos prevailed as people surged forward to leave the bridge.

Paramedics have taken the injured to a hospital, the police control room said.

Deadly stampedes are fairly common during Indian religious festivals, where large crowds gather in small areas with few safety or crowd control measures.
