DMK leader M K Stalin and other party leaders were detained after they staged a protest outside the Tamil Nadu assembly.
Stalin along with 86 other party leaders was evicted from the House after a pandemonium broke out inside the assembly on Wednesday morning when he demanded a debate on the alleged cash-for-vote scam.
Opposition DMK members tried to raise the issue of alleged horse trading of AIADMK MLAs ahead of the February 18 trust vote sought by Chief Minister K Palaniswami.
"I tried to raise the cash issue in assembly, but speaker didn't allow. This TN govt headed by Edappadi K Palaniswami should be dissolved," Stalin said.
Following this, 'MLAsForSale' placards were raised in the Tamil Nadu Assembly.
