Three U.S. law enforcement officials say a woman suspected of sending an envelope containing the poison ricin, which was addressed to White House and President Donald Trump, has been arrested at the New York-Canada border.
The officials say the woman was taken into custody by U.S. Customs and Border Protection (CBP) officers and is expected to face federal charges. The officials were not authorized to discuss the ongoing investigation publicly and spoke on condition of anonymity.
Aaron Bowker of the CBP confirmed with CBC News that the arrest took place at the Peace Bridge in Buffalo and that the individual was travelling from Canada into the U.S.
The letter had been intercepted earlier this week before it reached the White House.
An RCMP spokesperson told CBC News on Saturday that it was assisting the FBI in the investigation and that “initial information from the investigation suggests that the letter originated in Canada.”
