The victim's friend, who was on her menstrual cycle, was spared, and managed to call for help, said a TVBS report.

Officers were cited as saying that authorities came across a peculiar blog post, in which the author claimed to have dreamt of a man raping two female students after threatening them with a utility knife.

The post was quickly taken off shortly after the incident and officers have located the Internet Protocol (IP) address of the user, believed to be the suspect, noted police.

According to the description provided by the victims, the suspect is around 165 to 170 centimeters in height, said the report.
