WASHINGTON (AP) — Officials at Georgetown University say a substance in a dorm room has tested positive for ricin.

University Chief of Police Jay Gruber said in an email Wednesday that no one has reported any symptoms of ricin exposure since the possibility of ricin was reported Tuesday in McCarthy Hall.

Gruber said swabs were collected from the dorm room and analysis of those sample swabs did not show any biological threat agents.

The chief said the room was decontaminated and all areas of McCarthy Hall have reopened to students. He said there were no immediate threats to members of the Georgetown community.

FBI spokeswoman Jacqueline Maguire told The Washington Post that no arrests had been made, but an investigation continues.
