Lawyer: Courtney Love Back in Hospital
He declined to name the facility or to detail the specifics of Love's condition.
Rosenstein did confirm that a warrant for her arrest, issued by a Los Angeles judge last Friday (Love's 40th birthday), remains in effect after she skipped a hearing in a felony assault case, but she is not in custody.
A spokeswoman for the L.A. County District Attorney's Office says prosecutors have no information on Love's whereabouts.
Earlier Tuesday, Love's civil attorney, Robert Ring, said during an unrelated Santa Monica court hearing that Love was in an East Coast "institution" and that she had been appointed a legal guardian.
Ring also offered no specifics, other than to call Love "a troubled rock star." The hearing at which he appeared stems from a lawsuit alleging that she owes money to another legal firm that previously represented her.
Last Friday's scheduled arraignment was for an alleged April 25 altercation with a 32-year-old woman at the home of Love's ex-boyfriend and onetime manager, Jim Barber. Love reputedly came at the woman with a liquor bottle.
Rosenstein said Friday that Love was in hospital for a gynecological condition. New York newspapers showed photos of Love, distraught and dressed in a camisole, being carried on a stretcher in handcuffs from her Manhattan apartment by paramedics that day.
An ambulance reportedly was sent to Love's home when the city fire department received an emergency 911 call reporting a miscarriage. Love told police separately that she had had an abortion on Thursday.
Police were dispatched to her apartment after the building supervisor called to report that someone was tossing bottles from a window, but no arrests were made at that time.
