US authorities this Sunday arrested a woman suspected of sending a package of ricin poison to US President Donald Trump last week.
This person was intercepted at a border crossing in New York State while trying to enter the United States from Canada. The woman was carrying a gun, as reported by the US network CNN, which quoted a police officer.
Although the Royal Canadian Mounted Police have stated that they are unable to confirm or reject a possible arrest, they announced earlier this weekend that they are working with the U.S. Federal Police (FBI) on the case.
The presence of ricin, a very toxic substance extracted from castor beans, has been confirmed by two tests. All mail from the White House is sorted and analyzed in an off-site facility before it reaches the official residence and main work place of the President of the United States.
