A California Highway Patrol officer is under investigation after he allegedly forwarded nude photos of a female suspect to his phone.

Officer Sean Harrington, 35, is accused of sending six explicit photos of the 23-year-old woman to himself after he discovered them on her phone while she was being booked on DUI charges in August. The photos show the woman in a bikini and various states of undress, according to the Contra Costa Times.

"We've been investigating this for quite some time, the investigation is coming to a conclusion and we expect to make a charging decision this week," Deputy District Attorney Barry Grove told the newspaper on Wednesday.

Investigators said that the woman, who was booked with a BAC of .29 -- three times the legal limit -- may have voluntarily given her password to the officer, according to Daily Dot.

However, Harrington wasn't legally allowed to search the phone without a warrant.

Harrington, who has been on the force for five years, was reassigned to desk duty while the case is investigated. Although no charges were filed at press time, investigators said they are mulling five counts of felony computer theft. If Harrington is convicted of a felony, he won't be able to remain a police officer.

The attorney for the woman, who is not being named, is concerned that others may have obtained the photos of his client through Harrington.
