Police in Borno state arrested the five men, aged between 21 and 44, in September over the shirts. Authorities alleged the group had conspired to produce and wear them with the intention of breaching public peace, and charged them with criminal conspiracy, inciting disturbance, disturbance of public peace and thuggery.
Responding to criticism from human rights groups and activists, police later said the arrests followed a routine patrol during which officers found substances believed to be illicit drugs and other items on the men, and argued they were not being prosecuted for expressing their political views. Amnesty International said the men were supporters of the opposition African Democratic Congress (ADC), according to the AFP news agency.
Two weeks after the arrests, police in the northern state of Kano blocked access to the venue of a planned meeting by members of the same movement, citing concerns over public safety.
The cases highlight the contested line between security measures and political expression. Hassana Maina, a lawyer and activist, called the police action over the T-shirts "despicable." "It's very dishonest at best because the fight that we've had and the insecurity that has been caused, the solution to that is not to create a system ... that thrives on fascism where dissenting voices are not allowed to exist," she told DW.
Isa Sanusi, executive director of Amnesty International in Nigeria, said the clampdown represented a disturbing pattern of repression of the right to freedom of association and expression. "People are free to support or oppose a political party or candidate. It is unacceptable that just wearing a T-shirt can become a reason for arrest and detention," he told DW. "These actions carried out by police constitute an attack on democracy itself."
The "Tinubu Must Go" movement opposes President Bola Tinubu's administration and says it wants to mobilize Nigerians ahead of the January 2027 presidential election. Its grievances extend beyond leadership. Nigeria is facing one of its worst economic crises in recent times, with food prices at their highest level in over 20 years, high inflation and skyrocketing transportation costs. Across the north, insecurity remains pervasive, particularly in rural communities, where the Boko Haram insurgency has killed hundreds of thousands and displaced millions over more than a decade.
Activists point to a longer record of pressure on dissent. Social media critic Abubakar Idris, known as Dadiyata, went missing in August 2019 after armed men seized him from his residence in Kaduna State and has not been seen since. Hamdiyya Sharif, 18, was arrested and remanded in prison over a TikTok video criticizing the Sokoto State governor's handling of security, and charged in a Sharia court with using abusive language against Governor Ahmed Aliyu and "inciting disturbance." The management of Arewa House, a research and historical documentation center in Kaduna, also withdrew approval for the presentation of a book deemed critical of the government, citing operational issues.
Maina said Nigerians should reject the idea that opposing the government calls their patriotism into question. "Standing up against policies that you think [are] bad for the development of your country, I think it's patriotism at its finest," she told DW.
