Courtney Love (search) was charged with attacking a female friend of her former managers in April with a bottle and a metal flashlight, authorities said.

The felony charge of assault with a deadly weapon stems from an April 25 incident at the Los Angeles home of former manager Jim Barber (search). An arrest warrant for the rocker was issued Wednesday, district attorney spokeswoman Sandi Gibbons said Tuesday.

Love was not in custody, and it was unclear whether she had been served with the warrant. She has been charged in three additional cases, including two that occurred hours apart in October.

Her attorney, Michael Rosenstein, could not be immediately reached for comment Tuesday.

Authorities said cocaine and other opiates were found in Love's system after she was arrested for allegedly trying to break into the home of a former boyfriend in October.

Love pleaded guilty in Los Angeles Superior Court to a misdemeanor count of being under the influence of a controlled substance and agreed to enter a drug rehabilitation program in that case.

Love also faces felony charges in Beverly Hills Superior Court, where she is accused of illegally possessing prescription painkillers. She has pleaded innocent in that case and is scheduled to return to court June 17.

In May, Love was arraigned in New York City on charges of assault and reckless endangerment for allegedly hitting a fan with a microphone stand at a club on March 18.
