TERRE HAUTE, Ind. (WTWO/WAWV) — Threats of violence toward a judge reportedly caused a brief lockdown of Terre Haute City Hall on Monday morning.

That’s according to the Terre Haute Police Department, who said that the situation began at approximately 11:45 a.m. when officials began to receive multiple anonymous phone calls that threatened violence towards a judge.

Police did not release the name of the judge being threatened in the incident.

As a result, City Hall was put on lockdown while officers and detectives from THPD began an investigation.

As of 1:36 p.m. the lockdown had reportedly been lifted and City Hall is back open to the public.

Police said the investigation is open and ongoing, and that no further information would be released at this time.
