A British man admitted on Friday that he carried out an arson attack on a London commercial property linked to Ukraine, and that he had accepted pay from a foreign intelligence agency, in a case prosecutors have linked to Russia.

Jake Reeves, 22, pleaded guilty at London’s Woolwich Crown Court to charges of aggravated arson on the premises belonging to a “Mr X” on an industrial estate in east London in March.

He also admitted a charge under Britain’s new National Security Act (NSA) of obtaining a material benefit from a foreign intelligence service.

He denied a further charge under the NSA of engaging in preparations for an act endangering the life of a person or creating serious risk to the health or safety of the public, and prosecutors said they would not pursue that charge.

Last month another man, Dylan Earl, 20, also admitted carrying out the arson attack. He pleaded guilty to a preparatory act under the NSA, which was brought in last year to crack down on hostile activity by foreign states.
