In a detailed account shared on Monday, June 2, 2025, Mwangi described being blindfolded, stripped naked, and tied upside down.
He alleges that his captors applied lubricant to his rectum and inserted foreign objects, actions he attributes to directives from a Tanzanian state security official.
These events reportedly occurred after Mwangi was arrested in Dar es Salaam while attempting to attend the treason trial of Tanzanian opposition leader Tundu Lissu. He was later released at the Kenyan border.
Mwangi’s allegations have intensified scrutiny of Tanzania’s administration, which has faced criticism for increasing political repression.
Despite earlier promises to uphold human rights, recent actions—including the detention of opposition figures and foreign activists—have raised concerns among international observers. President Hassan has publicly warned foreign activists against interfering in Tanzania’s internal affairs.
The Tanzanian government has not issued a statement regarding Mwangi’s claims.
Meanwhile, human rights organisations are calling for an independent investigation into the alleged abuses.
Mwangi, currently receiving medical attention in Nairobi, continues to advocate for justice and accountability in the face of these serious allegations.
