The Office of the Special Prosecutor (OSP) has arrested Rev. Dr. Ammishaddai Owusu-Amoah, former Commissioner-General of the GRA; Isaac Crentsil, ex-Commissioner of Customs and now General Manager at SML; and Christian Tetteh Sottie, former Technical Advisor and now MD/CEO of SML, linked to ongoing investigations into suspected corruption and corruption-related offenses in respect of contracts between the GRA and SML for revenue assurance services.
The probe also aims to verify SML’s claims that its services have generated significant savings for the nation.
Owusu-Amoah, Crentsil and Sottie were detained last night after failing to meet bail conditions.
On June 9, 2025, Strategic Mobilisation Ghana Limited (SML) accused operatives from the OSP and National Security of dismantling its state-of-the-art real-time monitoring infrastructure—an act the company says could cost Ghana millions of cedis in lost customs revenue daily.
Images show how vital equipment of SML, including monitors, servers, computers, and other essential technology components, was ripped apart during the raid.
Inside SML’s operations centre, scenes resembled the aftermath of a break-in.

Background
The President had commissioned KPMG on December 29, 2023, to undertake an inquiry to gain a clear understanding of the matters in controversy and to be properly advised in taking the necessary decisions.
On May 22, 2024, then President Nana Addo Dankwa Akufo-Addo released the full KPMG report of the transaction between the Ghana Revenue Authority (GRA) and SML for public consumption.
A statement announcing the release said the President, “in the interest of full transparency in governance, openness, and honesty with the public, has decided to waive the privilege under section 5 of the RTI Act and has directed the publication of the KPMG report in full.”
On April 24, 2024, Nana Addo received a request from the Media Foundation for West Africa (MFWA), under section 18 of the Right to Information Act, 2019 (Act 989) (RTI Act), for a copy of the KPMG report on the contracts and transactions between GRA and SML.
The statement from the presidency said, bearing in mind the provisions of the RTI Act, particularly section 5(1)(a) and (b)(i) of the Act, the President denied the request by MFWA since the KPMG report constituted matters exempt under section 5 of the RTI Act.
“However, the President, in the interest of full transparency in governance, openness, and honesty with the public, has decided to waive the privilege under section 5 of the RTI Act and has directed the publication of the KPMG report in full,” it added.
