A woman has been charged with explosives offences after police raided a home in Cardiff.

Natalie Parsons, 51, faces two counts of making or possessing an explosive substance with intent to endanger life and four counts of possession of terrorist documents. She was due to appear at Westminster magistrates court on Monday.

Officers allegedly found triacetone triperoxide (TATP) in the fridge at a house in the Ely area of Cardiff when they raided it on Wednesday. Another explosive substance, hexamethylene triperoxide diamine (HMTD), was allegedly discovered in the garden shed.

Edward John Harris was previously arrested and charged with four offences of making or possessing an explosive substance with intent to endanger life. He is also charged with four terror offences relating to manuals on how to make and use explosives.

The 27-year-old appeared at Westminster magistrates court on Saturday. He was remanded in custody until 27 September when he will appear at the Old Bailey.

Counter-terror police said there was no evidence of a specific terrorist threat against the Welsh capital.

Det Supt Jim Hall, the head of the Wales extremism and counter-terrorism unit, 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.”
