A man accused of making high explosives in his home has appeared in court.
Police allegedly found triacetone triperoxide (TATP) in the fridge at Edward John Harris’s house in Cardiff when officers raided the address on Wednesday.
Another explosive substance, Hexamethylene Triperoxide Diamine (HMTD), was allegedly discovered in the 27-year-old’s garden shed, the court heard.
Harris is also charged with terror offences relating to manuals on how to make and use explosives, including one entitled The improvised Munitions Handbook.
Counter-terror police stressed there is no evidence of a specific terrorist threat against the Welsh capital.
Harris, of Archer Crescent, appeared at Westminster Magistrates’ Court on Saturday wearing a grey tracksuit, speaking only to confirm his name, date of birth, address and that his nationality is “white British” during a hearing lasting less than 20 minutes.
He is 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 and four charges of possessing a document containing information useful to terrorism under section 58 of the Terrorism Act 2000.
There was no application for bail and 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.
