Court documents alleged they conspired to import and sell prohibited firearms, including AK-47 rifles, PKT machine guns and ammunition to armed groups operating in Sokoto, Kebbi, Zamfara and Katsina states.
Owo church attack
On 3 June, the Federal High Court sentenced Idris Omeiza, Alqasim Idris, Jamiu Abdulmalik and Abdulhaleem Idris to death by hanging after their conviction over the 5 June 2022 attack on St. Francis Catholic Church, Owo, Ondo State.
The charge accused the defendants of belonging to a terrorist group, planning the attack and participating in the assault that killed more than 40 worshippers and injured over 100 others.
Court documents indicate that a fifth defendant, Momoh Otuho Abubakar, also faced charges in the case.
Previous wrongful detention reviews
The review of prolonged detention cases comes alongside the SSS's ongoing prosecution of terrorism and other security-related offences. The service says it has also continued to re-examine inherited cases to ensure that individuals wrongly detained are identified and released.
Among the cases is that of Nura Idris, a Kaduna herder who was released in June after spending about two years in SSS custody over alleged links to Boko Haram.
Following a review that found no basis for the allegations, the service ordered his release and paid him N3 million in compensation.
Earlier, Sunday Ifedi was freed in December 2025 after investigators found no evidence linking him to the proscribed IPOB. He received N10 million in compensation, while the SSS also announced plans to rebuild a restaurant owned by his late wife, who died in custody.
The service said it has reviewed more than 30 inherited cases and paid over N300 million in compensation to individuals found to have been wrongfully detained. Other beneficiaries include Abuja businesswoman Chineze Ozoadibe, who received N10 million after her release in October 2025, Kenneth Nwafor and five others wrongly linked to IPOB, as well as Ya'u Mohammed of Yobe State, who received a N2 million reintegration support package after investigations cleared him of terrorism allegations.
Pattern of prosecutions
The June convictions reflect an increasing reliance on coordinated mass trials to dispose of terrorism-related cases involving alleged members or supporters of Boko Haram, ISWAP and other violent groups, as well as prosecutions involving kidnapping, illegal arms trafficking and offences linked to IPOB.
The convictions come days after the Federal Government commenced another round of mass terrorism trials at the Federal High Court in Abuja.
On 15 June, the Attorney General of the Federation and Minister of Justice, Lateef Fagbemi, led the prosecution as more than 600 terrorism suspects were arraigned on charges including terrorism, membership of proscribed groups, terrorism financing and failure to disclose information on terrorist activities.
The latest proceedings followed an earlier phase of the mass trials conducted in April, during which government figures showed that 386 defendants were convicted, while two were acquitted and eight discharged. The June convictions formed part of that broader effort to prosecute terrorism-related offences through coordinated mass trials.
