Man extradited from Sweden to face charges in arson case targeting Jews

The brother of a man suspected in four events of arson involving Jewish institutions in the Boston area in 2019 has been extradited from Sweden to face charges alleging that he obstructed the investigation, US federal prosecutors say.

Alexander Giannakakis, 37, formerly of Quincy, Massachusetts, worked in security at the US embassy in Stockholm, Sweden, when he was arrested by Swedish authorities in 2022. He has been awaiting extradition proceedings, according to a statement from the US attorney’s office in Boston.

Giannakakis arrived in Boston on Friday and is scheduled to appear in federal court Monday afternoon, the US attorney’s office says. He has not yet named or been appointed an attorney, according to online case records.

Alexander Giannakakis’s brother was hospitalized in a coma at the time he was identified as a suspect in February 2020 and he died that year. Federal authorities did not name him.

Alexander Giannakakis was indicted by a federal grand jury in Boston in 2019 on charges of making false statements in a matter involving domestic terrorism; falsifying, concealing and covering up a material fact in a matter involving domestic terrorism; concealing records in a federal investigation; tampering with documents and objects; and tampering with an official proceeding.
