LAFAYETTE, La. (AP) _ Police at the University of Louisiana at Lafayette are investigating two racist messages found on campus this week. 
 
 KLFY-TV reports one racist slur was found on a banner inside a campus building; the nature of the second slur is unclear. Police spokesman Lt. Billy Abrams says the banner slur is being investigated as an act of criminal mischief. 
 
 The vice president of student affairs, Patricia Cottonham, says it was one of two racist messages found on campus this week. She says the hateful messages don't reflect the university, which has zero tolerance for racism and vandalism. 

 
 She says students found to be responsible for the slurs may be expelled and could face criminal charges. 

She asks for people with information on the racist messages to email tips to https://studentaffairs.louisiana.edu/dean-students.
