Arizona’s supreme court building was evacuated Monday morning after multiple vials that tested positive for a homemade explosive substance were sent to the building, according to the state’s department of public safety (DPS).

At about 8am local time on Monday, DPS responded to reports of a “suspicious package”. Later that morning multiple agencies, including the US bureau of alcohol firearms and tobacco responded.

Around 10.30am, staff at the Arizona supreme court building were sent home and the building was evacuated after a package in the building’s mailroom tested positive for explosives, 12News, Phoenix’s NBC affiliate reported.

The building sits about a mile west of the city’s downtown and the investigation into the package is being led by the state’s department of public safety, the Phoenix police department said.

Multiple buildings in the area, including the department of education, across the street from the supreme court building, were also evacuated, according to DPS.
