After nearly six hours of questioning by the Central Bureau of Investigation in Delhi, TVK chief Vijay on Monday told the premier agency that his party is not responsible for the stampede in Tamil Nadu that claimed 41 lives, sources have told NDTV. The stampede in Karur occurred on September 27 last year at a massive political rally addressed by Vijay, marking one of the deadliest crowd disasters in Tamil Nadu's recent political history. The actor-politician was not confronted with any other witness during today's questioning.
