Department of Homeland Security Deputy Press Secretary Brian Doyle busted! Doyle was charged with trying to seduce a child and transmission of harmful material to a minor.

Doyle, of Silver Spring, Md., had a sexually explicit conversation with what he believed was a 14-year-old girl whose profile he saw on the Internet on March 14, the Polk County Sheriff's Office said in a statement.

The girl was an undercover Polk County Sheriff's Computer Crimes detective, the sheriff's office said.

Doyle sent the girl pornographic movie clips and had sexually explicit conversations via the Internet, the statement said.

During other online conversations, Doyle revealed his name, that he worked for the Homeland Security Department and offered his office and government issued cell phone numbers, the sheriff's office said.

On several occasions, Doyle instructed her to perform a sexual act while thinking of him and described explicit activities he wanted to have with her, investigators said.

Doyle later had a telephone conversation with an undercover deputy posing as the teenager and encouraged her to purchase a web camera to send graphic images of herself to him, the sheriff's office said.

He was booked into Maryland's Montgomery County jail where he was waiting to be extradited to Florida, the sheriff's office said.
