Officials: Arrest made in ricin scare
An arrest has been made in connection with letters sent to President Barack Obama and Sen. Roger Wicker that authorities are testing to determine if they contain ricin, two federal law enforcement officials said Wednesday.
The person was arrested in the Tupelo, Mississippi, area, one of the officials said.
Discovered Tuesday, the letters were addressed to Wicker, a Mississippi Republican, and to Obama.
The letters were stopped at a government mail-screening facility after initial tests indicated the presence of ricin.
