Pittsburgh Police from Zone 4, the Pittsburgh Police Bomb Squad, the Pittsburgh Hazardous Materials Response Team, and the Spill Truck responded to the Community Day School in the 6400 block of Forward Avenue for reports of a suspicious package.

The package contained an unknown white powder and was delivered by mail a day earlier from an address outside of the country. It was reported to police just after 9 a.m.

None of the school staff or first responders experienced any adverse side effects from being in the vicinity of the substance.

The school was not evacuated during the response.

After conducting on site tests, the composition of the substance was not immediately determined.

FBI Pittsburgh removed the package to be tested with its equipment.

The investigation is ongoing.
