STORY HIGHLIGHTS
Arrest came in Tupelo, Mississippi area
Sources say the FBI expects to receive test results on letters Thursday
Envelopes were addressed to Obama and Sen. Roger Wicker, R-Mississippi
Initial tests on those envelopes detected the deadly poison ricin; additional tests under way
(CNN) -- 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.

Because initial tests can be "inconsistent," the envelopes have been sent off for additional tests, an FBI statement said. The FBI does not expect to receive results from the tests until Thursday, federal law enforcement sources told CNN.

The letters read: "To see a wrong and not expose it, is to become a silent partner to its continuance."
