Shannon Richardson has been arrested on suspicion of sending ricin-laced letters to President Barack Obama and New York Mayor Michael Bloomberg, a spokeswoman for the U.S. Attorney's Office in the eastern district of Texas said on Friday.

 

The letters, which were anonymous and sent last month, referenced the debate on gun control. A third letter, also containing ricin was sent to the director of Mayors Against Illegal Guns, a group founded by Bloomberg that lobbies for stricter gun laws.
