Boniface Mwangi Detained In Tanzania Amidst Treason Trial Of Opposition Leader

Dar es Salaam, Tanzania – Kenyan human rights activist Boniface Mwangi remains in detention in Tanzania following his arrest on May 19, 2025. Mwangi had traveled to Dar es Salaam to attend the high-profile treason trial of Tanzanian opposition leader Tundu Lissu, a case that has drawn significant international attention. His detention has sparked widespread concern in Kenya, with his wife making an emotional appeal for his release.

Mwangi, a renowned photojournalist and activist known for his outspoken stance against injustice, arrived in Tanzania alongside Ugandan journalist Agather Atuhaire to observe the court proceedings. Lissu’s trial is under international scrutiny due to allegations of political repression in the lead-up to Tanzania’s general elections scheduled for October.

Reports indicate that armed men, identifying themselves as police officers but refusing to show proper identification, took Mwangi from his hotel room. He was initially held at the Central Police Station in Dar es Salaam before being transferred to the Immigration Department. Conflicting reports regarding his deportation circulated, but as of May 21, 2025, Mwangi is confirmed to still be in Tanzanian custody.

The detention of Mwangi has ignited outrage among human rights defenders and civil society organizations across the East African region. Many view his arrest as part of a broader crackdown on dissent and political opposition within Tanzania. Mwangi’s wife, Njeri Mwangi, tearfully appealed for her husband’s release, highlighting his unwavering dedication to advocating for the rights of others. Mwangi is widely regarded as a fearless voice in the region, known for exposing human rights abuses and speaking out against corruption and oppression.

Human rights groups have condemned the detention, urging Tanzanian authorities to uphold Mwangi’s rights and adhere to international human rights standards. They warn that suppressing activists undermines democratic processes and freedom of expression. The Kenyan embassy in Tanzania is reportedly actively engaging with Tanzanian officials to clarify the reasons for Mwangi’s detention and ensure his well-being.

Other Activists Denied Entry and Deported

Mwangi’s situation is not an isolated incident. Other prominent figures attempting to enter Tanzania to observe Lissu’s trial have also faced immediate deportation. Former Kenyan Justice Minister Martha Karua was detained upon arrival at Julius Nyerere International Airport and, after several hours of questioning, was deported back to Kenya. Alongside Karua, former Chief Justice Willy Mutunga and human rights activists Hanifa Adan and Hussein Khalid, as well as lawyer Gloria Kimani and campaigner Lynn Ngugi, also faced similar treatment, being detained and sent back.
