HONOLULU -- One of President Obama's close friends from his native Hawaii is facing charges after being arrested during a prostitution sting in the state.

Robert Richard Titcomb, 49, allegedly solicited sex from an undercover police officer posing as a prostitute, Hawaii News Now reports. Titcomb was one of four arrested during the sting, Hawaii Police Department says.

Titcomb was released on $500 bail and will appear in court next month.

Obama and Titcomb have been close friends since high school, and the pair often get together to golf and dine when Obama vacations in the state, Hawaii News Now reports.
