Opposition leader MK Stalin and lawmakers from his party, the DMK, were detained together after they blocked traffic on a road outside the legislature after being evicted from the building. Mr Stalin wanted the legislature to urgently discuss a "sting" aired recently on private TV channels that shows some members of the ruling party, the AIADMK, discussing how much money they were offered for a crucial trust vote in February that allowed E Palaniswami to remain Chief Minister.
