A 20-year Denver International Airport employee began surfing for child pornography on the job after he became bored at work and irritated about getting old, according to an arrest warrant affidavit obtained by The Denver Post Wednesday.

Neil Cleary, who resigned his position in January, was charged earlier this week with felony sexual exploitation of a child.

The 64-year-old grandfather is free on $5,000 bail pending a July 3 court appearance.

The affidavit states that Denver police received a tip in December that Cleary, a contract compliance representative for DIA, had been viewing child pornography on his city-issued computer.

In an interview he gave to police in early January, Cleary said he had become consumed with pornography and was unable to stop looking at it. He told police that the pictures of children he was viewing were in the category of nude modeling, rather than sexually graphic photos involving children, the affidavit states.

Police found sexually explicit cartoons depicting children engaged in sex with adults and nude images of children who appeared to be between the ages of 7 and 16 photographed in “sexualized poses wearing swimsuits and panties” on various computers and hard drives at Cleary’s home, according to the document.

The browser history on Cleary’s work computer showed “numerous links which were indicative of pornography sites involving children,” the document states.
