Framingham State University officials are investigating two possible hate crimes targeting black students on campus, and the school is looking into a campus police officer’s comments on the graffiti.

The school’s campus police department is investigating the two possible hate crimes, which occurred Friday and Sunday inside Larned Hall, a residential building on campus that houses more than 350 students.

On Friday, graffiti that used the n-word was found on a flier for a meeting of the school’s Black Student Union. And on Sunday morning, “[n-word] live here’’ was found scrawled on a dorm room door.

If a student was responsible for the graffiti, they would face a school judicial hearing and punishment that could include expulsion, said university spokesman Daniel J. Magazu.

“Students who know Framingham State know we welcome difference. . . . This kind of behavior is really not acceptable,’’ said Magazu.

Magazu confirmed that the school is also investigating reports that a Framingham State campus police officer suggested to students that the racial slur found Friday was intended as a “friendly comment.’’

“If found to be true, it’s totally inappropriate and not in line with who we are as a university,’’ Magazu said.

The graffiti at Framingham State follows incidents earlier this month of racist graffiti on the Salem State University campus and a swastika and racial slurs reported at Rockland High School.

Markiyah Bullard, 20, a Framingham State junior and vice president of the Black Student Union, said Sunday’s graffiti appeared on the door of the dorm room used by two members of her group’s executive board.

Since the incidents occurred, Bullard said, she won’t walk around campus by herself.

“I do feel it’s created an unsafe environment; I do feel unsafe that someone can go out of their way to do this to someone else,’’ said Bullard.

Destinee Morris, 21, the group’s president and a university junior, said she was outraged that the graffiti occurred, and posted photographs of both incidents to Facebook, which had been shared about 100 times by Sunday afternoon.

“If people feel those harmful comments are right, they shouldn’t be on campus,’’ Morris said of the graffiti.

The Black Student Union has about 70 student members, said Morris, and holds campus events that explore the cultures of African-Americans and other groups.

The graffiti “angered me, because we welcome everyone to our club,’’ said Morris.

Toke Alabi, 20, a school junior and member of the union, said she was deeply hurt by the graffiti.

“I never really understood how people could hate you because of your skin color,’’ said Alabi. “I was not raised with that.’’

In a statement, F. Javier Cevallos, the university’s president, said a campuswide meeting scheduled for 1:30 p.m. on Monday will focus on the incidents and allow officials to address questions and concerns from community members.

Cevallos urged students to take advantage of campus resources, including counseling, clergy, and the school Center for Inclusive Excellence, according to the statement.
