33-year-old Jesse Andrew Green is charged with two felony counts of forcible sodomy in connection with the attacks.
In the first incident, Green is accused of going to the home of a 41-year-old woman he had been dating in April 2006, and sexually assaulting her against her will, according to Scarborough.
Santa Ana police asked prosecutors to file charges against Green after that incident, said Santa Ana police Cpl. Anthony Bertagna.
"They refused our case and we were done, but now they're re-submitting it," Bertagna said.
Scarborough said he could not comment about how prosecutors handled the case in 2006.
The second incident allegedly took place on Nov. 6, 2009 when Green took a 40-year-old woman to his Huntington Beach apartment.
Once inside his apartment, Green sexually assaulted the woman while she screamed and struggled to get away, Scarborough said.
He allegedly met the woman through a mutual friend and they were on their first date.
Both victims were reluctant to report the assaults to law enforcement, fearing retaliation, Scarborough said.
Green is scheduled to be arraigned in the West Justice Center on Wednesday.
He faces 16 years in prison if convicted on both counts.
Authorities are asking anyone with additional information or who believes they have been a victim to contact Supervising District Attorney Investigator Randy Litwin at 714-347-8794 or Huntington Beach Police Detective Michael Szyperski at 714-536-5988.
