Former Australian betting syndicate leader Bill Vlahos is facing over 300 counts of financial deception for allegedly defrauding hundreds of investors between 2008 and 2013.

Yahoo 7 News reported that Vlahos, who formerly headed up the BC3 Thoroughbreds ownership group, appeared in Melbourne Magistrates Court last Thursday to answer allegations that he swindled millions of dollars from people who invested in betting syndicate, The Edge.

The prosecution will present more than 80 witnesses during the course of Vlahos’ four-week pre-trial, which will start on March 5. A pre-trial is conducted in order to determine whether the betting syndicate leader should stand trial.

Among those expected to present evidence before the court is the head of Ladbrokes Australia.
