A man has admitted having “improvised paintball grenades” after telling police he was preparing for the apocalypse.

Scott Porter, 43, pleaded guilty to possessing an explosive substance and information useful to a person preparing an act of terrorism at the Old Bailey on Tuesday.

Police found the homemade grenade devices, which were filled with glass, metal and chilli powder, during a raid of his home in Haywards Heath, West Sussex in October 2019.

They also found other weapons including crossbows, knives and knuckledusters.

Porter told police he had the dangerous items in case an apocalyptic scenario occurred.

Judge Mark Dennis QC described it as an “unusual case” and said the defendant was “in his own world”.

He asked for reports to be prepared on the seriousness of the offences, as well as the motivation and potential dangerousness of the defendant.

He remanded him in custody ahead of sentencing on 29 October.

Detective Chief Superintendent Kath Barnes, head of counter terrorism for the South East, said: “During this investigation it was clear the information found in the possession of Porter would have been useful to someone who wanted to cause harm to our communities.

“Although Porter didn’t have a specific ideology, the information he wrote, researched and designed could have been useful to a terrorist with plans to carry out an attack.

“His actions were reckless and the weight of evidence against him left Porter with no choice but to plead guilty to these serious offences.”
