Mevani was arrested by the Assam Police from Gujarat late on Wednesday, 20 April, for two of his tweets on Prime Minister Narendra Modi and Nathuram Godse that went viral and allegedly "pose a threat to disturb tranquillity".
Twitter withheld the two tweets in question in response to a legal demand. Mevani, the convenor of the Rashtriya Dalit Adhikar Manch, was later flown to Assam.
Meanwhile, Mevani's lawyers told the media after the court order that they would appeal to a higher court seeking his bail.
Earlier on Thursday, Assam Chief Minister Himanta Biswa Sarma said he was not aware of Mevani's identity or arrest. The Assam police also refused to share the detailed reasons for his arrest.
"I was not allowed to inform my family members of the arrest. This is in violation of the Supreme Court guidelines where a person is entitled to know the charges he is facing in the FIR," he said.
The complaint against Mevani, filed by local Bharatiya Janata Party (BJP) leader Arup Kumar Dey at Kokrajhar Police Station, stated that the 41-year-old leader, in one of his tweets, had said, "PM Modi worships Godse" and "...that the PM on his Gujarat visit must make an appeal for harmony in light of the recent events of communal violence in the state".
Mevani, who had extended support to the Congress last year, was apprehended from the Palanpur Circuit House at around 11:30 pm. He was later flown to Assam and taken to Kokrajhar police station.
According to news agency ANI, the FIR against the leader has been filed under IPC sections 120B (criminal conspiracy), section 153(A) (promoting enmity between two communities), 295(A) (deliberate and malicious acts intended to outrage religious feelings of any class by insulting its religion or religious beliefs), 504 (intentional insult with intent to provoke breach of peace), and various sections of the IT Act.
