ATHENS, Greece (AP) — Greek prosecutors say a 29-year-old man arrested in Athens has been charged with attempted murder against former Greek Prime Minister Lucas Papademos.

The suspect was charged Sunday with joining a terrorist group, Conspiracy Cells of Fire, assembling and posting a letter bomb to Papademos with the intention of killing him.

Also, based on what police found in his apartment — firearms, bullets, detonators, explosives, timers, fake IDs and hashish — he was charged with possession of firearms and explosives in order to commit terrorist acts and supply terrorist groups, forgery, theft and drug possession.

Papademos, 70, the prime minister in 2011-12 and the deputy governor of the European Central Bank from 2002-2010, was seriously injured on May 25 when he opened a letter bomb. He was hospitalized for over a month.
