CBS affiliate wbztv.com, reported that a Holliston, Mass. man is accused of sending a bomb threat letter to the Van Nuys Airport in California that included a reference to Foster, according to FBI officials.
FBI agents said that Michael Smegal, 42, sent the threatening letter from Holliston last December. The handwritten letter was delivered to Van Nuys Airport's administration building saying there was a gas bomb that was going off.
Prosecutors said Smegal had admitted sending letters and packages to Foster in 2004 and had promised to stop.
They said DNA samples from three of the letters sent in recent months matched the material sent to Foster.
Smegal was released from jail under the supervision of his father and is not allowed access to U.S. Mail or the Internet, the U.S. Attorney's Office said. In addition, he is not allowed to make any unsupervised phone calls and must have no contact with Foster, wbztv.com reported.
Foster has won two Academy Awards, as well as a pair of Golden Globe awards, three British Academy of Film and Television Arts and a Screen Actors Guild Award.
The 45-year-old actress has starred in "Taxi Driver," "The Accused," "Silence of the Lambs," "Contact," "Panic Room" "Flightplan" and "Inside Man."
Smegal did not immediately return a call seeking comment. The 42-year-old faces up to 10 years in prison and a $250,000 fine.
A hearing is scheduled for Smegal on March 31.
