A state judge sentenced a 41-year-old state Department of Transportation employee to 10 years in prison Monday for first-degree electronic enticement of a child.

In February, Russell H.L. Loo admitted in court that he used the Internet to arrange a meeting to have sex with someone whom he believed was 15-year-old girl; the “girl” was an undercover police officer. Loo’s admission was part of a plea agreement.

Loo also pleaded guilty to five counts of indecent electronic display to a child. Each count for that offense brought a one-year sentence, which Circuit Court Richard Pollack said would be served at the same time as Loo’s 10-year sentence.

Police arrested Loo on Oct. 3, 2010 when he showed up to meet the “girl” at an arranged meeting place at Waiau District Park.
