Washington: A close friend of US President Barack Obama has been arrested on a prostitution charge in Hawaii.
Hawaii News Now has reported that Robert Richard Titcomb, 49, allegedly solicited sex from an undercover police officer posing as a prostitute.
Hawaii Police Department say Titcomb was one of four arrested during the sting, reports Fox News.
Titcomb was released on USD 500 bail and will appear in court next month.
Obama has been friends with Titcomb since high school, and the two often get together to golf and dine when Obama vacations in the state, Hawaii.
