One day after San Diego Police Chief William Lansdowne publicly apologized for a series of police misconduct cases, another city cop was arrested on six felony counts involving the rape of a prostitute, officials said.

Daniel Dana, 26, a patrol officer in the department's Western Division, was arrested Wednesday and booked into San Diego County Jail at about 2 p.m. on charges of kidnapping and rape under the color of authority, according to the Sheriff's website. He is scheduled to be arraigned on charges including assault by a public officer, oral copulation under threat of authority, kidnapping to commit rape or robbery and other charges.

"I'm outraged. I'm doing my best to control my composure," said San Diego Police Chief William Lansdowne.

The incident that led to Dana's arrest took place in Presidio Park at about 3 a.m. Wednesday, a police source told Fox 5 News. A 34-year-old woman told police that Dana, who was on duty at the time, raped her and forced her to give him oral sex. The woman told investigators that she and Dana had developed a friendly relationship in recent weeks and that he sent her a text message to meet him early Wednesday.  When they met, Dana threatened to arrest her if she didn't have sex with him. She reported the incident to police afterwards.

Dana served with the San Diego Police Department in its Western Division for about four years, according to officials. He was no longer a member of the force after his arrest, they said, but they didn't say whether he resigned or was fired.

"I believe that we're taking the right steps in this case," said Lansdowne "Officer Dan Dana is no longer a member of the San Diego Police Department. "

According to information posted on a personal website, Dana is a native of Washington state. He served in the Marine Corps as a Corporal, and he was based at Camp Pendleton. The website also state's that he lives in Escondido and he married in April 2006.

"We're in the process now of doing the search warrants for his police vehicle, for his personal locker and some other items," said Lansdowne.

The latest police scandal comes a day after Lansdowne personally apologized to the city of San Diego for the recent spate of alleged misconduct by officers in his department. Lansdowne said Dana was given a refresher course on the department's conduct policy just days ago.

"He was personally talked to by the captain of Western Division two weeks ago," said Lansdowne. "Then he was personally talked to by the sergeant who supervises the team that he works for last night because of the press conference."

According the Sheriff's website, he is currently being held in downtown's Central Jail. He is scheduled to be arraigned on Friday afternoon at 1:30, according to the website.
