The legislator, who was arrested after the clash at Palakurthy in Warangal district on Sunday, was produced before the court in Jangaon. Police also presented 20 others arrested in the case.
The clash broke out when Dayakar Rao arrived with his supporters at a function where Deputy Chief Minister Kadiam Srihari was inaugurating a new building at Palakurthy market yard. The two groups pelted stones and hurled chairs at each other.

Dayakar Rao, who is the TDP leader in the Telangana assembly, and his supporters were subsequently arrested and were lodged in a police station for the whole night.
The opposition party alleged that the ruling party leaders and activists attacked Dayakar Rao and his followers. It alleged that the protocol was not being followed in the constituencies represented by the opposition legislators.
