A man has appeared in court after being charged with explosive offences and possessing terrorist documents.
Edward John Harris, from Cardiff, was arrested following reports of explosive materials being held at an address in the Ely area of the city.
Counter-terror police stressed there is no evidence of a specific terrorist threat against the Welsh capital.
Harris appeared at Westminster Magistrates’ Court on Saturday charged with four offences of making or possessing an explosive substance with intent to endanger life or cause serious injury to property, under Section 4 of the Explosives Act 1883.
He also faces four charges of possessing a document containing information useful to terrorism under section 58 of the Terrorism Act 2000.
District Judge Margot Coleman remanded him in custody until September 27 when he will appear at the Old Bailey as part of the court’s so-called terror list.
Detective Superintendent Jim Hall, the head of the Wales Extremism and Counter Terrorism Unit (WECTU) said: “Our investigation continues but we must stress that there is no evidence to suggest any specific terrorist threat against Cardiff or that people in Cardiff are at any greater risk, however we would remind people to remain vigilant and report any suspicions to the police.”
Police said a second suspect remains in police custody for questioning.
