(AP) -- Two people were shot on the UCLA campus Wednesday, but the conditions of the victims were not yet known, a university spokeswoman said.

Campus media relations officer Rebecca Kendall said she did not know the whereabouts of the shooter.

The campus on the city's west side was locked down, and university and Los Angeles police officers were moving around with weapons drawn. More than a dozen police cars massed near Boelter Hall, an engineering building.

Los Angeles Officer Tony Im would only say that the department's officers are responding to a report of an active shooter.

The shooting occurred the week before final exams at the school, the flagship of the University of California system with about 43,000 students.

Boelter Hall is near the center of a campus that occupies 419 acres in a bustling part of Los Angeles.
