According to official sources, the team was led by NCSC Assistant Director (Chennai) P Ramasamy.
The issue took a serious turn after one of the three injured in the incident on January 16 died two days later.
Police registered a case under the Prevention of Atrocities against SC/ST Act against 20 persons from Arasapatti village and DSP of Tirumangalam D Arasu investigated the matter and arrested four persons.
The team met the injured at the Government Rajaji Hospital here and handed over Rs 75,000 relief to them.
Armed police have been posted in the village to monitor the situation.
The attack was the sequel to a dispute between two groups over a temple festival a couple of months ago, police said.
