Students and staff are not at risk and the school was not evacuated, he said.

Police were called to the school at 9:29 a.m., after the staff member opened the package containing unknown letter from an unknown individual, Gaithersburg police officer Dan Lane told Patch.

The teacher notified police when he found an unknown substance inside, Lane said. Fire and Rescue officials say there is no Hazmat concern.

The substance was sent to a lab for testing, and police "will know the results at a later date," Lane said.

Marquis Drive was closed for a short time while police investigated the package.
