Agrawal and Nayak were arrested last night, but were later released on bail bond, police said.
A clash broke out between supporters of School Education Minister Brijmohan Agrawal and Congress candidate Kiranmayee Nayak when they were brought together on a common platform by a news channel for its political show on Wednesday night, Raipur Superintendent of Police O P Pal said.
Nayak is pitted against Agrawal from Raipur South constituency in the upcoming assembly elections.
BJP as well as Congress supporters present at the venue soon jumped on to the dais and flung chairs. However, they were soon pacified by the police, Pal said.
Since the show was being broadcast live, the clash was caught on camera, police said.
Later, Nayak lodged a case against Agrawal and his supporters, while the ruling party workers also registered a counter case, he said.
