Princedeep used objectionable language against the erstwhile royal who represents Guna Lok Sabha seat and threatened to shoot him if he visited Hatta, he said.
The post shared on Facebook read, "Jyotiraditya Scindia, you have Jiwajirao's blood running in your veins, who killed Jhansi ki, Rani. If you step in Hatta then I will shoot you. Either you will die or I will.
The FIR was lodged by Youth Congress leader Anurag Vardhan Hazari, the officer said.
He said Princedeep was brought to the police station by his MLA mother.
He has been booked under various sections of the IPC, Singh said.
Jyotiraditya Scindia slammed BJP and Madhya Pradesh Chief Minister Shivraj Singh Chouhan after one of the ruling party MLA's son threatened to shoot him.
"The mentality of the BJP leaders and real face of the party have been exposed with this threat," Scindia told ANI. He further said, "The main objective of the party and Chief Minister Shivraj Singh Chauhan is to demolish Congress at any cost."
Making it clear that such a threat will never throw him or his family into a panic, Scindia stated, "I would like to tell them that the Scindia scion never bowed down to such threats and will never do that as well."
Scindia is scheduled to visit Damoh district on September 5.
Condemning the post, former Madhya Pradesh chief minister Digvijay Singh said the incident showed the "real face" of the BJP and RSS.
State unit Congress spokesman Pankaj Chaturvedi demanded that the government strengthen Scindia's security if needed.
