Singer Amy Winehouse was allegedly detained on suspicion of attempting to interfere with a court case involving her husband.
Police would not confirm the report but said a 24-year-old was arrested during an appointment at a police station in connection with an investigation into perverting the course of justice.
Winehouse, 24, recently canceled all concerts and public appearances for the rest of the year on doctor's orders. Her husband, Blake Fielder-Civil, was ordered held in custody in London last month on charges of perverting the course of justice stemming from a case in which he is accused of assaulting a barman in June.
Fielder-Civil allegedly tried to interfere with a witness' testimony, according to court documents.
Winehouse, an admitted marijuana smoker, has been dogged by reports of continued drug use amid a flurry of canceled concert dates. She was recently spotted walking outside of her London home wearing a bra and jeans, with no shoes, looking distressed.
The bodies of two Russian women were found in Turkey's Bodrum. The killer tied the bodies and wrapper them in sheets before getting rid of them
