Federal authorities have charged Dave Herman — who ruled the morning 1970s rock airwaves as a renowned disc jockey at New York's WNEW-FM — with trying to transport a 7-year-old Bergen County girl to the Virgin Islands to sexually abuse her.

Herman, now 77, who lives in both Airmont, N.Y. and St. Croix, was arrested earlier today by U.S. Immigration and Customs Enforcement agents at the St. Croix airport, said U.S. Attorney Paul Fishman in a statement.

Herman is scheduled to appear tomorrow before U.S. Magistrate Judge George W. Cannon in St. Croix federal court, authoritities said.

Federal authorities, citing documents filed in the case, allege that starting in November 2012, Herman initiated a series of chats on a Web site with a female undercover officer from the Bergen County Prosecutor’s Office.

According to authorities, Herman thought he was communicating with a 36-year-old single mother -- she referred to herself as "Kris" -- who had a 6-year-old daughter she called "Lexi."

During the following months, Herman then had multiple phone and online discussions with the undercover officer, during which he indicated that he wanted to engage in sexual activity with the officer’s fictitious daughter "Lexi."

He also attempted to arrange sexual encounters with the child in both New York and Bergen County, authorities added.

Then in early 2013, Herman told "Kris," the undercover officer, that he would like to fly the her and her daughter to St. Croix to spend a few days with him so he could have sexual activity with the girl, authorities said.

On Sept. 30, 2013, according to authorities, Herman purchased airline tickets for them to fly from LaGuardia Airport to St. Croix.

On the criminal count of attempting to transport a minor in interstate commerce with the intent she engage in sexual activity, Herman faces is a mandatory minimum of 10 years in prison and a maximum penalty of life in prison, if convicted, authorities said. The charge also carries a maximum $250,000 fine, they added.
