Banks witnessed more crowd as many ATMs ran out of cash, while serpentine queues were seen outside those which were dispensing money.
Political parties, including DMK and VCK, have opposed the Centre's decision to mark bank customers with indelible ink to check people coming back again and again.
The government's this move came in the wake of some people reportedly trying to convert black money into white and having organised groups of people and sending them from one branch to another to exchange notes.
CPI(M) state secretary G Ramakrishnan and hundreds of party workers were taken into custody during protests in different parts of the state including Chennai, Tirunelveli and Dindigul.
Ramakrishnan and others were taken into custody for trying to picket the RBI office here.
