The CBI had summoned Balaji on allegations that his visit to the venue during the rally was planned, allegedly creating confusion among supporters and the public.
TVK chief and actor Vijay's rally in Karur on September 27, 2025, resulted in a massive stampede that claimed 41 lives and left more than 60 people injured.
The agency, which questioned Vijay twice in January, had again summoned the actor on March 9, but he had requested that it be deferred by 15 days, they said.
