Toxic letters sent to Bloomberg from Shreveport
SHREVEPORT- Officials say two threatening letters sent to New York City Mayor Michael Bloomberg contained traces of the deadly poison ricin and were postmarked May 20 from Shreveport.
New York City police said Wednesday the anonymous letters were opened Friday in New York at the city's mail facility and Sunday in Washington at an office used by the nonprofit started by Bloomberg, Mayors Against Illegal Guns. Both were addressed to Bloomberg and contained threats referencing the debate on gun laws.
Police say preliminary testing indicated the presence of ricin.
Police say civilian personnel who came into contact with the letters were not showing any symptoms, but some officers who later examined the one in New York were.
The Louisiana Governor's Office of Homeland Security and Emergency Preparedness said they are working with federal law enforcement agencies in the investigation.
