A 33-year-old former Maui police officer was arrested yesterday and charged with sexually assaulting a man when he was on duty in Kihei last year and with assault and impersonating a police officer in connection with another incident.

Lewis Gamble, who joined the Maui Police Department in 2005, was arrested yesterday on a bench warrant and charged with four separate counts.

Maui police said that two of the charges, sexual assault in the first degree and kidnapping, stem from an incident that occurred March 9 while he was on the job in Kihei.

On March 29, Gamble  was involved in a confrontation which led to a fight. He was charged with assault in the third degree, impersonating a police officer and false reporting.

The Maui News reported that a 41-year-old man reported being sexually assaulted by Gamble in early March last year after Gamble responded to the man’s home in Kihei to investigate a burglary report. The man said that Gamble, then a Kihei patrol officer, was in uniform and carrying a gun.

The man also reported being chased and tackled by Gamble three weeks later in Wailuku town.

The Maui newspaper also reported that without naming the officer, an MPD report on internal investigations concluded in October said an officer was suspended for 15 work days and terminated from employment for committing a criminal act in March 2010.

Gamble was fired from the Maui Police Department in October, said Maui Lt. Wayne Ibarra.  Maui officials declined to discuss specifics of his charges and the reasons for his dismissal.

He is free on $250,000 bail.
