- Mahesh Hegde was charged for spreading fake, communally sensitive news
- PM Modi is among those who follow Mr Hegde on Twitter
- The portal had been charged with posting content inciting communal hate
Mr Hegde's arrest is based on his tweet on March 19 on an accident involving a Jain monk. His portal had reported that Upadhyaya Mayank Sagar Ji Maharaj was hit by a drunk biker, who is Muslim. "Very sad news, yesterday in Karnataka Jain muni attacked by Muslim youth. No one is safe in Siddaramaiah's Karnataka," the editor had said in the tweet that was on the Postcard News handle and was retweeted several times. Prime Minister Narendra Modi is among those who follow Mr Hegde on Twitter.
The portal had earlier been charged with publishing content that incites communal hate.
In December, Postcard News had published a controversial article on a legendary 18th century Chittor Queen, Chennamma, which provoked much outrage.
The opposition BJP in the state has condemned the editor's arrest.
"The arrest was a deplorable move by the Siddaramaiah government," said BJP parliamentarian Pratap Simha.
