Senior DMK leader and former minister K Ponmudi was on Saturday arrrested in connection with a red sand quarrying case, police said.
Police said Ponmudi was picked up from his residence in Villupuram district, over 160 km from Chennai.
The Madras high court had on Friday rejected his anticipatory bail plea.
Based on a report given by the Tahsildar of Vanur in Villupuram, police had registered a case for alleged offences under Mines and Minerals (Development and Regulations) Act, 1957, Tamil Nadu Mines and Minerals Concession Rule, 1959, Prevention of Corruption Act, 1988 and IPC.
The case relates to alleged irregularities in quarrying of red sand in 'patta' lands in the area.
Ponmudi, who was handling portfolios of higher education, mines and minerals in the previous DMK regime, is the party strongman in Villupuram district.
