A Bogra court on Wednesday sent Gazi Salahuddin Tanvir, the recently suspended joint member secretary of the National Citizen Party (NCP), to jail in a case filed over making a derogatory Facebook post about Prime Minister Tarique Rahman.
Judge Mehedi Hasan of Bogra Senior Judicial Magistrate Court passed the order.
Bogra Sadar police arrested him from the Monipur area of Dhaka on Tuesday night, said Sadar Police Station Officer-in-Charge Ibrahim Ali.
According to police and the case statement, Tanvir made the post following an alleged attack on an NCP street rally in Sylhet several days ago. The post triggered widespread reactions among BNP and its affiliated organisations’ leaders and activists.
Tanvir later deleted the post from Facebook and apologised. However, screenshots of the post circulated widely on social media and other platforms. The NCP subsequently suspended him from party activities and issued him a show-cause notice.
On August 2, Bogra Sadar upazila BNP President HS Maftun Ahmed Khan Rubel filed a case against Tanvir under the Cyber Security Act, 2026.
In the case statement, the complainant said he saw the Facebook post around 3pm on July 29 while at the Bogra district BNP office. He alleged that Tanvir had made defamatory and provocative comments targeting Prime Minister Tarique Rahman from his personal Facebook account.
The complainant said the post caused negative reactions among the public. Although it was later deleted, he alleged that the post amounted to an attempt to defame the prime minister and create confusion among the public. Several BNP leaders and activists had also seen the post on Facebook, the case statement added.
This marks the second time Tanvir has been suspended from the party. He was first removed in April 2025 following allegations that he interfered in deputy commissioner appointments after entering the secretariat in the aftermath of the July mass uprising and that he was involved in commission dealings related to textbook printing contracts with the National Curriculum and Textbook Board (NCTB).
He remained outside the party for about a year before being reinstated on April 16 this year. His latest suspension comes roughly three and a half months after his return.
Shortly after the controversy broke, Tanvir posted on his own Facebook account expressing regret over his remarks.
