KANSAS CITY, Mo. (AP) — A federal grand jury has indicted a Kansas City corporate executive on charges of child pornography and trying to entice a minor over the Internet for sex.

The U.S. attorney's office says Wednesday's indictment of 37-year-old Daniel C. Irwin followed a nearly eight-month investigation by an undercover Kansas City police detective.

Prosecutors say Irwin, an assistant vice president at a financial services company, tried to persuade the undercover officer to let him have sex with the officer's purported daughters. Irwin also is accused of sending the officer a number of images of child porn.

Irwin was arrested Aug. 8 after a search warrant was executed at his home. His attorney was not available for comment Wednesday.
