Detectives say they recovered, among others two unused tear gas canisters and one 7.62mm blank round from activist Boniface Mwangi’s office in Nairobi.
This was during a search in his office on Saturday July 19.
Mwangi was arrested by detectives at his residence in Lukenya in Machakos County in connection with the facilitation of terrorist activities during the June 25, 2025, protests, police said.
During the arrest, detectives recovered two mobile phones, a laptop, and several notebooks.
He was later escorted to his office at Mageuzi Hub, Rose Avenue in Hurlingham, where a search led to the recovery of nine assorted external hard drives, two laptops, company seals for Brave Media Ltd and Courage Ltd, a company stamp, six cheque books, copies of stamp duty documents, two unused tear gas canisters and one 7.62mm blank round, a statement said.
Mwangi was detained at Pangani Police Station for offences related to facilitation of terrorist acts and unlawful possession of ammunition.
Mwangi is under investigations over claims of among others arson, robbery with violence and money laundering.
He has denied the claims and termed them politically motivated.
A search warrant issued by a Magistrate’s Court in Nairobi showed the detectives from the Serious Crimes Unit at the Directorate of Criminal Investigations headquarters are among others investigating him over claims of malicious damage to properties, incitement to violence, arson, robbery with violence, money laundering and related offences.
His wife also mentioned the detectives are investigating him over claims of terrorism.
This is the latest trend in which the detectives are targeting those who participated in the recent protests and have charged them with among others terrorism.
The search warrant was issued on July 17. It showed the police were targeting Mwangi’s property including his home in Lukenya, Machakos County to open, search, have access, seize, remove and carry away, his documents, electronic storage devices including servers, computer systems, security safes, money and any containers, and all relevant articles/items for the purposes of carrying out investigations on the offences.
Mwangi and Agather Atuhaire, a Ugandan lawyer and journalist have filed a petition at the East African Court of Justice (EACJ) against the governments of Tanzania, Uganda, Kenya, and the Secretary General of the East African Community.
In the petition, they are seeking “full accountability” and redress for what they describe as unlawful arrest, inhumane treatment, and deportation while attempting to attend the trial of Tanzanian opposition leader Tundu Lissu.
The suit, filed as reference No. 21 of 2025, follows a sequence of events on May 18–19, 2025, when Atuhaire and Mwangi traveled to Dar es Salaam as part of a larger delegation of journalists, lawyers, and activists from across the East African region intending to observe Lissu’s treason trial.
