to the 1993 Yorkshire Television documentary The Hidden Hand: The Forgotten Massacre, driven to a farm in Glenanne, County Armagh. This farm, which had been used to make and store the bombs, was owned by Royal Ulster Constabulary (RUC) reservist James Mitchell of the Glenanne gang. After the cars were delivered to the waiting bomb unit, the latter drove them across the border down to the Coachman's Inn pub carpark. Journalist Joe Tiernan suggested that the cars were driven directly to the North Dublin carpark, with only one stop in Portadown by one of the cars to collect David Alexander Mulholland, one of the alleged bombers. It was at the carpark that the three bombs, which had been transported in a chicken lorry by senior Mid-Ulster UVF member Robin "the Jackal" Jackson, were placed inside the boots of the cars by Hanna and Jackson. The cars – a metallic green 1970 model Hillman Avenger and blue Austin 1800 Maxi – that ended up in Parnell Street and South Leinster Street had been hijacked while the metallic blue mink Ford Escort which detonated in Talbot Street had been stolen from Belfast's docks area. All three cars had retained their original registration numbers. The Hidden Hand: The Forgotten Massacre named Marchant as having been on a Garda Síochána list of suspects as the leader of the gang which obtained the bomb cars. Ninety minutes after the Dublin blasts, another car bomb exploded in Monaghan, causing a further seven deaths. A detective from Dublin's Store Street Garda Station received confidential information that Marchant had masterminded both the Dublin and Monaghan attacks. On 26 May, he was arrested by the Northern Ireland security forces under the Northern Ireland (Emergency Provision) Act 1974 and interned at the Maze Prison on an Interim Custody Order partly on suspicion of having participated in the car bombings. He was interrogated by detectives but refused to reply to any questions relating to the Dublin bombings. Marchant and the others who had also been interned as suspects in the attacks, were never brought to trial due to lack of evidence. The RUC Special Branch, in a reply dated 23 July 1974 to an earlier Garda enquiry regarding Marchant, stated that Marchant "was our guest for a number of hours (and CID) but with negative result".
