Southern Methodist University issued a crime alert after a student reported being sexually assaulted.
Early Sunday morning, a male student told police he was sexually assaulted by another male student at two different locations, first along fraternity row and then in a parking garage, across the street.
It is the fourth sexual assault reported by SMU this year.
In late August, a female student said she was sexually assaulted by a stranger, outside the entrance to a building in the law quad.
There was another alleged assault in May. A woman reported she was raped by an SMU student, in off-campus housing in the 3200 block of Rosedale.
Earlier this month, an SMU student was indicted for raping a female student in February, in a freshman dorm.
While there have been four sexual assaults reported by SMU in 2012, there were 2 in 2011, and 1 in 2010.
"It seems like a high number," said SMU law student, Kristina Hashler. "It's pretty scary, especially because we have classes at night."
Other students reported seeing increased security.
"I do feel safe, I don't have concerns," said law student, Kelsey Taylor. "After the most recent assault over here, I definitely noticed campus security had stepped up."
SMU released the following statement to NBC 5:
SMU takes all allegations of sexual assault seriously and its police department vigorously investigates all such complaints. The alleged sexual assault reported to SMU Police on Sept. 23 is under police investigation. SMU seeks to help students, faculty and staff avoid being victims of crime by notifying them whenever there is criminal activity, or suspected criminal activity, that may threaten their safety.
