A University of Washington student has been arrested for allegedly making threats to kill women and comparing himself to Elliot Rodger, the gunman who killed six people and then himself near the University of California, Santa Barbara.

The 23-year-old, who has not been charged, was ordered held on $150,000 bail Monday after a judge found probable cause to hold him for investigation of felony harassment, as KIRO Radio first reported.

According to court documents, the student drew the attention of local and federal agents after posting threats to commit “lewd and lascivious acts” in comments on YouTube, Google+ and other websites.

Using the pseudonym “Foss Dark,” prosecutors alleged the student wrote in one exchange on June 5, “I am the next elliot rodger, and gues what ill do the right thing this time, ill make sure ill only kill women [sic].”

Another commenter suggested “Foss Dark” seek out an escort service rather take out his anger on women as Rodger did in California. Before the shooting, Rodger expressed frustration with his inability to meet women and develop relationships in a series of videos and posts.

In his online exchange, the UW student wrote that he had to kill women because “nothing can compromise for an ugly face and short stature, I will execute the same thing. I have no option [sic].”

With the assistance of FBI agents, University of Washington police began investigating the student after a June 9 post in which he identified himself as a Seattle resident and student on the campus after commenters told him to take responsibility for the crimes he planned to commit.

“I live in seattle and go to the UW, that’s all I’ll give you. I’ll make sure I kill only women, and many more than what Elliot accomplished [sic],” he wrote.

According to documents, the FBI was able to link the

name “Dark Foss” to an individual living in Seattle. University Security Services tracked a computer address attached to one of the posts back to the student.

Two UW police officers and two FBI agents found the student at his residence in the University District late Sunday night and arrested him on suspicion of felony harassment and cyberstalking.

According to police, the student admitted to authoring the posts.
