WASHINGTON (Reuters) - Authorities have arrested a person suspected of sending the deadly poison ricin in an envelope addressed to the White House but intercepted before it could be delivered there, a law enforcement source said on Sunday.
In response to a Reuters query seeking confirmation of media reports that a woman accused of mailing the ricin-tainted letter had been taken into custody at the U.S.-Canadian border, the FBI field office in Washington issued a statement saying: “An arrest was made of an individual allegedly responsible for sending a suspicious letter."
