Actress Kim Delaney, who played an alcoholic detective on "NYPD Blue," was arrested over the weekend on suspicion of drunken driving, police in Malibu said. According to reports, Delaney, 40, was busted outside her home at 7:50 p.m. Saturday after a witness driving behind her rang authorities on his cell phone to say that her vehicle was moving erratically. "He followed her to the house," Los Angeles County sheriff's department Sgt. Peter Charbonneau told Reuters. "Deputies arrived at the house. She ultimately came out, and the citizen identified her as the person who was driving." Delaney refused to take a blood alcohol test, said the officer, and she was taken to the Malibu sheriff's station, where she booked on suspicion of driving under the influence. She was later released after being served with a notice to appear in court, Sgt. Craig Barnes of the Los Angeles County Sheriff's Department told the Associated Press. She is set to appear at a hearing on March 27. The 1997 Emmy winner for her role as Det. Diane Russell on ABC's "Blue" (her steamy love scenes with costar Jimmy Smits also got a lot of attention), Delaney left the show last year to star in "Philly," in which she plays Kathleen Maguire, a feisty lawyer and single mom. She got her acting start on ABC, appearing on the soap "All My Children."
