The jury convicted UK residents Nii Mensah, Jakeem Rose and Ugnius Asmena of aggravated arson today.

The east London attack targeted a Ukrainian businessman’s warehouse where SpaceX-made devices and generators were stored in March last year.

The attack was orchestrated by Dylan Earl on behalf of the mercenary organisation Wagner Group, prosecutors said at trial.

Earl and Jake Reeves previously pleaded guilty in the case.

All five men are between 20 and 23 years old.

“These convictions send a very clear message that this type of offending will not be tolerated on UK soil,” David Cawthorne, crown prosecution service’s counter terrorism division head said.

London’s Metropolitan Police charged the men last year, making it the first case successfully bought under the National Security Act.

The 2023 law gave authorities more powers to prosecute modern spying activities and widened what could be considered as threats to national security – including theft of trade secrets.
