Section 144 is imposed in Karnataka's Mandya ahead of the Supreme Court's order on Cauvery dispute.
The Supreme Court today will hear the plea on directions to both Tamil Nadu and Karnataka to take preventive measures, in the matter of the Cauvery water dispute.
Meanwhile, Section 144 has been imposed in Mandya's Sanjay circle ahead of the Supreme court's order.
Karnataka Home Minister G Parameshwara has issued guidelines to the police, directing them to take precautionary measures.
He has also directed the police to keep ready fire engines and required emergency forces at sensitive areas around Cauvery belt including Bengaluru.
The police has also been directed to flag march around sensitive areas and an appeal has been made to pro-Kannada activists and farmers' associations to maintain peace.
The Supreme Court had earlier on September 5 asked the Karnataka government to release 15,000 cusecs of Cauvery water to Tamil Nadu on a daily basis for the following 10 days.
However, protests intensified in Karnataka and Tamil Nadu post the top court's order.
The Karnataka government later on September 17 filed a plea asking the Supreme Court to modify the order.
In response, the top court pulled up both states, asking the people "to behave", and turned down the plea.
The top court later on September 12 reduced the quantity of water to be released from 15,000 cusecs to 12,000 cusecs till September 20.
