TULSA, Oklahoma - Oklahoma's Attorney General has charged a 50-year-old Tulsa businessman with two counts of securities fraud.

Robert Eugene Tucker is currently serving a 10-year suspended sentence after pleading guilty last year to practices similar to the charges filed Wednesday.

In the 2014 case, Tucker was also ordered to pay $37,500 in restitution to victims and perform 500 hours of community service hours.

In a news release, Attorney General Mike Hunter began an investigation after a complaint was referred his office by the Oklahoma Department of Securities.

In this latest complaint, Hunter states it is alleged a Tulsa resident attempted to invest in Robert Tucker’s company, Corporate eXchange International.

During their investigation, agents with the AG's Consumer Protection Unit determined Tucker targeted a victim and sold a six-month note for $15,000, promising a return of $17,107.19. 

In the release, the Attorney General's office said when the note was due, the victim made several attempts to contact Tucker, who gave multiple excuses as to why he could not pay. Mike Hunter states, eventually, all attempts to contact Robert Tucker were unsuccessful.

The Attorney General's office says in 2011, Tucker also entered into a Consent Judgment with the Oklahoma Department of Securities, which stopped him from selling securities in the state.
