Louisville Mayor Greg Fischer signed an executive order Tuesday that places the city under a state of emergency as Louisville awaits a grand jury decision in the case of Breonna Taylor, an emergency medical technician who died in a police raid at her apartment this year.

Fischer's order would allow him to impose a curfew and a variety of other restrictions under his emergency powers "due to the potential for civil unrest," according to a release from his office. The order follows a memo from Louisville Metropolitan Police Chief Robert J. Schroeder on Monday telling officers the department would be employing emergency guidelines effective immediately.

"In anticipation of Attorney General Daniel Cameron's announcement in the Breonna Taylor case, I am declaring a state of emergency for the Louisville Metro Police Department (LMPD)," the memo said.
