A Rhode Island state senator under investigation by state police since January was arrested Friday on charges of video voyeurism and extortion.

Republican Sen. Nicholas Kettle faces one count of video voyeurism brought by state police for sending pictures of his ex-girlfriend’s “private parts,” Lt. Col. Joseph Philbin said. He also was indicted on two counts of extortion, but Philbin said he could not comment on those counts.

Kettle was being held in jail over the weekend and is to appear in court today.
