A senior police officer said that based on intelligence reports, security had been increased at Singh's bungalow. There were reports of some miscreants stoning Singh's residence, but police dismissed them as rumours.
Meanwhile, Singh's scheduled visit to Ratlam to take part in a Congress rally has been cancelled. The rally will be addressed later in the day by B K Hari Prasad, the Congress general secretary in-charge of Madhya Pradesh; and the party's state unit president, Kantilal Bhuria.
The Congress leader had on Sunday justified the police crackdown on Baba Ramdev's fast against corruption in New Delhi on Saturday and accused him of "inciting people".
Terming the yoga guru as a "fraud", Singh had also demanded an inquiry into the "thousands of crores of rupees" of property owned by Ramdev.
"Don't bring any politics in this. The kind of treatment needed to be meted out to a fraud has been meted out to him," Singh had said.
Singh, however, on Monday said he never had the intention of courting controversies.
The former Chief Minister was in the news on Sunday after he justified the police crackdown on Baba Ramdev's fast against corruption in Delhi and called the yoga guru a "fraud".
"It is not my intention to enter into any controversy. I only speak about facts and the truth," he said. Singh said he would speak the truth even though it drags him into controversies.
The Congress general secretary said it would be unfair to brand him as a man who relishes controversies or likes to stir them up.
"The fact that I have never been pulled up by the top leadership indicates that my statements have never caused any problem to the government," he said.
