A 75-year-old retired teacher has been arrested by German police on charges of organizing a far-right terrorist plot and plotting to kidnap Germany’s health minister, The Guardian and Politico reported.

A 75-year-old woman arrested in Germany is suspected of leading a group that planned kidnappings and attacks on a power plant, and procured weapons and explosives to destroy the country’s power grid, German authorities said.

According to German media, the arrested woman was identified as Elisabeth R., a professor of theology at the University of Mainz, who worked as a Protestant pastor and planned to kidnap Health Minister Karl Lauterbach.

The retiree was anti-vaccination and allegedly promoted conspiracy theories about COVID-19, accusing Lauterbach of taking too hard a line during the pandemic.

Four other members of a group called United Patriots, led by Elizabeth R., were also arrested, authorities said.

The group’s goal was to incite a civil war in Germany and restore the German Empire in 1871, authorities added.

Elizabeth R. signed an open letter in which she argued that the Treaty of Versailles had not been legally implemented and that a parliamentary monarchy still existed without an emperor since October 28, 1918.
