The 35-year-old man charged with 14 terrorism related offences worked at the City of Lincoln Council.
David Parnham was arrested on Tuesday by Counter Terrorism Policing North East after a raid at his home and his office at City Hall.
He was then charged with 14 offences on Thursday, including soliciting murder and a bomb hoax related to ‘Punish a Muslim Day’ activities.
Parnham also allegedly sent fake poisoned letters and encouraged others to hurt muslims.
He was in a junior administration role at the City Council.
Angela Andrews, Chief Executive of City of Lincoln Council, said: “We have been assisting the police with their investigation over the past week and can confirm that an employee of City of Lincoln Council has now been charged following his arrest on June 12.
“We are all deeply shocked by these events and the allegations against the member of staff. These alleged views and actions do not reflect the values or culture of City of Lincoln Council in any way whatsoever and, if true, are confined to the individual.
“Unfortunately, as this is a live investigation and court proceedings are active, we are not able to say anything further at this time.”
