VILNIUS, Lithuania (AP) — A Lithuanian judge found an Irish man guilty Friday of trying to buy weapons and explosives in a six-year sting orchestrated by Britain’s domestic spy agency MI5 — a case that drew attention to a hardcore Irish Republican Army splinter group’s plans to spread terror to London.

Judge Arunas Kisielus of the Vilnius Regional Court sentenced Michael Campbell — a 39-year-old with alleged links to the Real IRA group — to 12 years in prison for weapons offenses and supporting a terrorist group.

Video footage and intercepted communications showed that Campbell paid some euro6,000 (about $8,300) for high-grade explosives, grenade launchers, detonators, AK-47s and a special assassin’s rifle to Lithuanian agents posing as arms dealers.

In an audio recording, he is heard discussing how easy it would be with the type of equipment on offer to plant a bomb in London and escape.

“You can imagine us getting over to England … You imagine, with a six-hour timer, we could be over to London and back,” Campbell says in an audio clip after mulling over a price list for explosives and detonators. “Just tick, tick, tick, tick … gone.

Kisielius sentenced Campbell to five years for weapons possession, six years for attempting to smuggle weaponry and explosives, and 12 years for supporting a terrorist group.
