The regime promulgated the State Security (Detention of Persons) Decree Number 2 of 1984, which gave the NSO the power to detain anyone suspected to be a security risk indefinitely. Detention under decree 2 was in 3-month tranches renewable at expiry. Another draconian decree was the Decree Number 4 which made it a punishable offence for anyone to publish any material deemed embarrassing to a government official, two journalists from The Guardian newspapers, Nduka Irabor and Tunde Thompson were jailed under this decree. On 11 April 1984, NSO operatives arrested Irabor and Thompson. They were tried by a military tribunal headed by Justice Olalere Ayinde and charges of falsely accusing public officers of the Federal Government. This was sequel to the summons issued by the Special Military Tribunal. The summons given to them on 2 June 1984 read: Form 2 Public Officers (Protection Against False Accusation) Decree No. 4 of 1984 summon to accused. "That you Tunde Thompson and Nduka Iraboh of The Guardian Newspaper, Limited, Rutam House, Isolo on April 1, 1984 at Rutam House, Isolo in Lagos, did publish “False statement contrary to section 1(1) of the Decree No. 4 of 1984.
