LOS ANGELES — An investigation was underway Tuesday after two UCLA students said they were drugged while attending several parties near the Westwood campus.

According to a UCLA Police Department crime alert issued Monday, the case was classified as "off campus aggravated assault use of drugs" and the locations were listed as the 500 block and the 600 block of Gayley Avenue.

According to the alert, on Saturday and Sunday, police learned about the crimes when "two victims reported unrelated incidents of being drugged with unknown substance(s) while attending parties."

"On (Thursday), victim 1 attended 3 parties at different locations on Gayley Avenue and developed symptoms which they did not believe were from alcohol," the report stated.

"On (Saturday), victim 2 attended a party on the 600 block of Gayley and, after being handed a drink, developed symptoms they did not believe were from alcohol/marijuana. No suspect descriptions (were) provided. The victims are UCLA Students. Victim 2 sought medical treatment at the ER," the report stated.

No vehicles were seen in connection with the crimes, according to UCLA police.

Some students who spoke with a local news station said this isn't typical behavior at the school.

"This is something that does not regularly happen at UCLA, and should not happen on any college campus across America," Chima Oluo said.

Students said they received mandatory safety training, but it was important to look out for one another.

"That's why you always keep in contact with your friends, always make sure you know where they are," student Lauren Wilbur told the station. "I have my roommate's location so I kind of check, but it's good to have a roommate like that so you know someone's watching your back."
