The arrest comes barely a day after Njiru launched a scathing attack on President William Ruto over the Head of State’s pledge to channel more than Ksh10 billion worth of development projects to Ol Kalou ahead of the constituency’s by-election.
In his remarks, Njiru accused the President of using development projects as a political tool, arguing that public resources should not be tied to election campaigns.
The lawyer further claimed that the government’s timing in announcing the projects amounted to political tokenism, expressing confidence that voters would distinguish between sustained development and last-minute campaign promises.
Njiru has, in recent months, emerged as one of the most outspoken critics of the Kenya Kwanza administration and has frequently represented Gachagua in court, including in legal proceedings challenging the former Deputy President’s impeachment.
Earlier this month, the advocate announced plans to move to the High Court over the National Transport and Safety Authority’s instant traffic fine payment system.
The planned petition followed public concern over motorists being directed to make payments bearing individual names instead of government entities.
However, the NTSA dismissed the claims, explaining that the names belonged to authorised banking agents facilitating the transactions and insisting that the payment system was legitimate.
Njiru’s arrest also comes amid heightened political activity involving leaders associated with the opposition, where he has been a regular figure alongside Gachagua, Kalonzo Musyoka and Justin Muturi during public rallies and strategy meetings.
By the time of publication, none of the senior opposition leaders, including Gachagua, Kalonzo or Muturi, had publicly commented on Njiru’s arrest, while police had yet to provide further details beyond the alleged obstruction incident.
