A narcotics-vice police officer accused of aiding a North Shore gambling ring has pleaded guilty in a plea agreement with federal prosecutors.

Glenn Miram pleaded guilty to conspiring to and obstructing law enforcement by warning of a police raid of the Waialua gambling operation, which included cockfighting and casino-style games.

Attorney William Harrison said his client, a seven-year veteran of the police department, chose to plead guilty rather than put his family through a trial.

"He obviously is contrite," he said. "He is the first one of the police officers that has taken responsibility, and I think that says a lot for his character."

In court papers filed Thursday, Miram admitted to conspiring with fellow officers Kevin Brunn and Bryson Apo.

Harrison said his client has an excellent chance of avoiding jail given his coming forward and acknowledging his complicity.

Prosecutors agreed to ask for a sentencing reduction. He now faces up to five years' imprisonment and a $250,000 fine when he is sentenced April 2 by U.S. District Judge Susan Oki Mollway.
