In Coventry, fires in four department stores began and were attributed to incendiary devices, balloon bombs being suspected. The stores affected were Marks & Spencer, Owen & Owen Ltd, the packing department of Montague Burton Ltd, and Woolworths. In Bristol, guns were issued to police after the discovery of a note in a petrol storage depot reading "BEWARE. These tanks are the next to be blown up". Watches were put on Avonmouth Docks and Bristol Airport. Arrests were made and seven hand-grenades, gelignite, ammunition, and the S-Plan document itself were seized. The S-Plan is thought to have been found on a detained IRA volunteer.

The second measure, called the Offences against the State Act, made it possible for citizens to be interned without trial, and conferred elaborate powers of search, arrest, and detention upon the police. It declared seditious any suggestion in a newspaper or magazine that the elected Government of Ireland was not the lawful government. The IRA had been declared an illegal organisation under the Constitution (Declaration of Unlawful Association) Order passed 18 June 1936, but the Irish Free State Government had only used this power on a few IRA volunteers. Éamon de Valera spoke about the IRA and S-Plan in the Dáil for two hours. He said that the IRA had no right to assume the title "Irish Republican Government" and that the then Irish Minister for Justice, PJ Ruttledge, planned to bring "energetic measures" before the house to combat
