Real estate moguls Oren and Alon Alexander will be held without bond ahead of their sex crimes trial, at least for now, a Florida judge ruled Thursday.

Twins Oren and Alon, along with their brother Tal, face federal and state charges. The siblings, two of whom have made billions of dollars in trades, have an international reputation as glamorous socialites.

Prosecutors claim the twin brothers, along with their older brother, drugged, sexually assaulted and raped dozens of victims.
