Mr. Alexander’s brother, Oren Alexander, was granted a hearing extension by a judge in Miami. A third brother, Tal Alexander, was denied bail on related charges in December.

The brothers were charged in New York with luring, drugging and violently raping dozens of women over more than a decade.

Prominent real estate broker Oren Alexander will have to wait until next week to see if he'll be allowed to leave jail, while his twin brother was denied bond during a hearing in federal court in Miami on Friday.
