BROCKTON — A Brockton man with two open rape cases is now charged with using nude photographs and videos of a Bridgewater State student in an attempt to force her to have sex with him.

Kevin Fortes, 24, was arrested on Monday and charged with extortion, destroying evidence from official proceeding, attempting to commit a crime (rape) and unauthorized access to a computer system.

Fortes pleaded not guilty Monday during his arraignment in Brockton District Court.

Judge Mary Amrhein set his bail at $25,000 on the new case, but allowed a motion from the Plymouth County district attorney's office prosecutor to revoke Fortes' bail on an open case.

The Bridgewater State University Police Department began an investigation last Thursday when a female student reported a case of blackmailing and possible sex trafficking. The woman told police that she had been communicating with a person on Snapchat who was using the name of a woman, Caroline, who claimed to be the friend of a man she had sexual relations with between October and November of 2019.

The woman told police she had received a message from the account sometime before last Thursday, but that she hadn't opened it. When she opened it last Thursday, she learned the person was asking her if she wanted a "gig," Detective Sgt. Robert McEvoy wrote in a police report.

"(The woman) explained that during her conversations with Caroline, she learned that Caroline set up women with men for sex and the women would be paid for the sex," the report states. "(The woman) stated that Caroline was trying to recruit her to have sex with a man for money."

The woman told the person through Snapchat that she was not interested, but said it appeared to "enrage" the person. The woman said the person then told her that she had hacked her Snapchat account and was in possession of numerous photos and videos of her having sex with a man. The person behind the account threatened to release the images on a Bridgewater State mobile app if the woman did not "have sex with a man of her choosing," the report states.

The Caroline account sent two photos via Snapchat to the woman that showed her having sex with a man, the report states. The person said the "gig" would involve the man in the pictures.

Police say they learned the woman had previously had sex with several men in which she consented to pictures and videos being taken. She also confirmed she had sex with the man seen in the videos in the threatening message, the report states.

Police say they learned at that point that the man in the photos and videos was Fortes. The woman said she had met him in October 2019 and had sex with him several times at his home in Brockton, allowing him to record the encounters.

The woman told police that, around Thanksgiving last year, she told Fortes she would no longer have sex with him and ended all communication. They didn't have any communication, she said, until the Snapchat messages last week.

Fortes told the woman he was planning to leave the country to play soccer and that he wanted to have sex with her one more time before leaving, the report states. He again threatened the woman and said he would release photos and videos of her if she did not comply with his request, it states.

The woman told police she had been saving all the messages in the chat to bring them to investigators, but she noticed at some point that all the messages she had saved had been deleted. She told police the only other person who could delete them was Fortes because he had access to her account.

On Monday, Bridgewater State police were granted a search warrant for Fortes' 20 Owens Ave. home in Brockton. He was arrested at the home.

"Kevin Fortes is known to me through a past investigation that led to his arrest for the charges of rape and extortion," McEvoy wrote. "During the last investigation, I learned that Fortes uses a tactic to extort his victims into having sex by threatening to release nude photos of the victims to the victim's friends, family and public if the victim does not have sex with him."

Fortes has two open rape cases in Brockton Superior Court — one for an offense that allegedly occurred on Oct. 14, 2017, in Bridgewater, and another on Oct. 24, 2018, in Brockton.

Fortes faces three counts of rape and three counts of extortion by threat of injury in those two cases. He had been scheduled to go on trial on March 2 related to the 2017 Bridgewater incident, but prosecutors on Monday requested that the date be canceled in light of the new charges. A new trial date is now set for June 1. There is no trial date scheduled in the 2018 Brockton incident.

Fortes is due back in Brockton District Court on March 19 for a probable cause hearing related to Monday's arrest.
