Five people struck a student in the face and took his clothes in Dickson Plaza early Thursday morning while thousands of students participated in UCLA’s “Undie Run.”

The incident happened around 12:20 a.m. and no injuries were reported, according to a crime alert UCPD sent out to students. The incident happened around the same time as the Undie Run, a tradition that involves students running from the intersection of Strathmore Drive and Gayley Avenue to Dickson Plaza in their underwear at midnight the Wednesday of finals week.

The student whose clothes were stolen contacted the police and reported that he did not know the people who stole his clothes, said Jeffrey Chobanian, the acting captain of UCPD’s administrative bureau, in an emailed statement. The alert listed five suspects as being involved in the crime, two of whom were described as men in their 20s.

No arrests were made regarding the incident, Chobanian said in the statement. 

“When thousands gather for an unauthorized event, the risk of crime increases,” Chobanian said in the statement. ”UCLAPD maintains a visible presence to deter criminal activity and uses data from past events to strategically position security and police officers in high-traffic areas.”

Campus administrators – including Mick Deluca, the associate vice chancellor for campus life – previously told members of the Undergraduate Students Association Council that policing procedures for high-profile events, including the use of student affairs monitors, would be used for the run. 

However, UCLA Media Relations did not respond to a request for comment on how the run would be policed and how students would be kept safe. The run also happened amid heightened security on campus Tuesday through Thursday due to a UC Board of Regents meeting at the Meyer and Renee Luskin Conference Center.

Chobanian said in the statement that he does not advise students to participate in the tradition, which was founded in the 2001-2002 academic year.

“Since the Undie Run is unauthorized, I recommend that students refrain from participating,” he said. “If you choose to participate, travel with a group of people and do not invite friends who are not affiliated with UCLA.”
