NEW DELHI - A couple in New Delhi died when the heavy-set wife tumbled and fell onto her husband while running up a staircase, Tamil Nesan reported.
They lived on the ground floor of an apartment complex and had become worried when their daughter-in-law rushed into their home to get medication for her son.
Concerned about the boy who lived on an upper floor, they followed the daughter-in-law up the stairs.
The 68-year-old woman, who reportedly weighed 128kg, slipped and fell backwards onto her husband, seriously injuring both of them.
The couple were rushed to hospital but died of internal bleeding shortly afterwards.
The daughter-in-law was hospitalised after she broke an ankle trying to help the couple.
