Amnesty International has raised alarms over threats to the safety of two human rights defenders in Imo State, Nigeria, urging authorities to investigate and protect the activists.

The global rights organization expressed deep concern for Okechukwu Nwanguma, Executive Director of the Rule of Law and Accountability Advocacy Centre (RULAAC), who has reportedly faced intimidation linked to his exposure of alleged atrocities at the Tiger Base police detention facility in Owerri.

Similarly, Nonso Nkwa, an independent radio broadcaster and activist in Owerri, has reportedly received threats for his investigative work highlighting alleged human rights violations at the same police unit.

Amnesty International described the threats as part of a broader, worrying trend across Nigeria, where journalists, whistleblowers, and rights defenders are increasingly harassed, intimidated, or detained for exposing corruption or abuses.

“The safety and security of Okechukwu Nwanguma and Nonso Nkwa is now at risk,” Amnesty said. “Threatening them for exposing injustice is unacceptable.”

The organization called on Nigerian authorities to immediately investigate the threats, ensure the protection of both men, and hold those responsible accountable.

Tiger Base, operated by the Nigeria Police Force in Owerri, has long faced scrutiny from civil society groups, but campaigners say meaningful accountability remains largely absent.
