Amy Winehouse was arrested Tuesday on suspicion of attempting to interfere with a court case involving her husband.
Police questioned the 24-year-old singer and released her without filing charges, her publicist said in a statement.
"She attended a police station voluntarily and at a pre-agreed time," the statement said. "She was arrested but that is common practice for someone being interviewed by police."
Police wouldn't identify the singer by name but confirmed a 24-year-old had been arrested during an appointment at a police station in connection with an investigation into attempting to interfere with the course of justice.
