A university in Vietnam has vowed to tighten security after an outsider managed to sneak into its main campus in Ho Chi Minh City and died from jumping off a tall building in an apparent suicide attempt on Friday, the latest in a string of similar incidents involving non-students this year.

The victim is a woman around 25-30 years old who has not been identified, Dr. Phan Hong Hai, vice rector of the Industrial University of Ho Chi Minh City (IUH) where the suicide took place, told Tuoi Tre (Youth) newspaper on Saturday.

Footage from CCTV cameras shows the woman standing outside the school’s campus in Go Vap District at around 3:00 am on Friday.

At around 3:25 pm, she sneaked into the campus through a door that had been left open by a sanitation worker who came to collect garbage.

She climbed all the way to the ninth floor of the tallest building on campus, where she sat on the balcony for a while before throwing herself off the building.

Her body was discovered at 4:15 am the same day by a janitor, who notified security guards.

“We have been able to confirm that the victim is not one of our students,” Hai said.

“As she didn’t carry any identification paper, we have not been able to identify the victim,” he added.

The campus of IUH is notorious for suicides by both students and outsiders, having been the site for four successful suicide attempts since the start of this year. All of them, including three non-IUH students, died on the spot following the suicide jumps.

Hai said the school is looking to tighten security and install new fences on its top floors to prevent such tragic incidents in the future.

“We will also offer more psychological counseling to students to help reduce suicidal tendencies,” Hai said.
