**Toxic Chemical Procurement Scandal: Ribadu's Office Responds to El-Rufai's Allegations** A recent exchange between former Kaduna State governor Nasir El-Rufai and the Office of the National Security Adviser (ONSA) has left many Nigerians wondering about the fate of a highly toxic chemical allegedly procured by the security office. The controversy began when El-Rufai wrote to the National Security Adviser, Nuhu Ribadu, claiming that a supplier in Poland had delivered 10 kilograms of thallium sulphate to the ONSA. However, in a letter dated February 13, 2026, Brigadier-General O.M. Adesuyi, on behalf of the ONSA, denied any involvement in the transaction. The letter, which was eventually delivered to El-Rufai's Abuja residence after an initial attempt was rebuffed by security personnel, stated that the ONSA had neither procured nor initiated any process for purchasing the chemical. According to the correspondence, the matter has been referred to the Department of State Services (DSS) for a thorough investigation. The NSA's office emphasized that El-Rufai and any other individuals with relevant information will be contacted as part of the probe. "Your Excellency and other parties involved, who may possess relevant information relating to this claim will be duly invited by the Service to provide any evidence that may assist in an in-depth investigation," the letter read. This exchange comes amidst separate claims by El-Rufai that he had intercepted a phone conversation involving Ribadu, in which he allegedly instructed security operatives to arrest him. While the authenticity of these claims is yet to be verified, they have added fuel to the fire, sparking widespread interest and debate in the country. As the investigation unfolds, many Nigerians are left wondering about the implications of this scandal. Will the DSS uncover any evidence of wrongdoing? Will El-Rufai's claims be substantiated or debunked? Only time will tell. One thing is certain, however: the controversy has highlighted the need for transparency and accountability in our security agencies. In conclusion, the recent exchange between El-Rufai and the ONSA has raised more questions than answers. While the NSA's office has denied any involvement in the procurement of the toxic chemical, the investigation is ongoing, and the outcome remains uncertain. As Nigerians, we can only wait and see how this saga unfolds and what lessons we can learn
