In an application filed in the trial court to oppose Mr Silveira's bail plea, the crime branch said that it is in the process of tracking all Facebook groups and their members with links to the accused, who has been remanded in two-day police custody.
"The accused had contested the Assembly polls from Panaji and had lost to Mr Parrikar. The accused used the social media to post his ill-feelings," Police Inspector Rajan Nigalye said in his application before Panaji Judicial Magistrate First Class Vijayalaxmi Shivolkar.
Mr Parrikar had polled 9,862 votes whereas Mr Silveira got only 96 votes.
"In the past also, there have been instances in other parts of the country wherein such posts on the social media have created doubts, ill-feeling and animosity in public mind, leading to loss of life, and public and private property, thus damaging the social fabric of the nation," the Crime Branch said.
In subsequent messages, Silveira accepted that his Facebook message was incorrect after other commentators informed him but he did not delete the message.
The FIR was filed by the Crime Branch following a complaint by the Bharatiya Janata Party Panaji unit chief Deepak Mhapshekar.
