US tycoon Robert Durst arrested over Berman murder
He was held in New Orleans after a warrant was issued by Los Angeles police investigating the murder of Susan Berman.
Mr Durst is the subject of HBO's The Jinx, which is investigating three unsolved murder cases linked to him.
The show says it has new evidence implicating him in Berman's shooting.
The 71-year-old had been previously questioned by police investigating her execution-style killing.
Mr Durst will appear in a New Orleans court on Sunday but his lawyer says he will not oppose being transferred to Los Angeles.
In 2003 he admitted killing Morris Black, dismembering his body and throwing the remains into a bay in Galveston, Texas, but a jury accepted his claim of self-defence.
The property heir was also questioned by police following the disappearance of his first wife Kathleen in 1982 in New York.
Mr Durst has always denied any involvement in the deaths of his wife or Miss Berman.
