(AP) -- A prosecutor's spokesman says millionaire real estate heir Robert Durst has been indicted on two weapons charges from his March arrest in Louisiana.

Chris Bowman of the Orleans Parish district attorney's office said Wednesday that a grand jury charged Durst with possession of a firearm by a felon, and possession of a firearm and a controlled dangerous substance.

His arrest related to those charges has kept Durst from being extradited to Los Angeles, where he's charged in the 2000 death of friend Susan Berman.

Until his indictment Wednesday, Durst had been arrested but not formally charged.

According to testimony, an FBI agent recognized Durst in a New Orleans hotel March 14 and escorted him to his hotel room. Durst was arrested March 15 on the Los Angeles warrant and arrested separately on the weapons charges the next day.

A hearing in the New Orleans case is scheduled for Thursday.
