Rashtriya Janata Dal chief Lalu Prasad Yadav sustained minor injuries after a stage he was standing on collapsed at an event in Patna on 24 March.
The incident occurred when the RJD chief was attending a Yajna in the city's Digha area at around 7pm.
As Yadav walked towards his seat, the temporary
structure collapsed, throwing the 68-year-old to the ground. According to reports, the stage collapsed after a crowd of devotees clambered up onto the structure.
Yadav complained of a back pain and was rushed to a hospital where an X-ray ruled out a fracture. He returned home late on Friday night.
