Referring to Raja's remarks reported in a section of media in this regard, SIFCI President L Suresh said that the BJP National Secretary had "confessed" this in a section of the media.
SIFCI is the apex body of studio owners, producers, distributors and exhibitors from all the southern states.
Raja "confessed before a press reporter that he saw the aforesaid Tamil film on the internet, which is obviously a pirated version," Suresh said in a statement.
"We have also written an official letter addressed to Prime Minister Narendra Modi and Union Information and Broadcasting Minister Smriti Irani, requesting them to take suitable action against Mr H Raja for seriously violating the Piracy Act," he said.
