The University of California-Davis has been at the center of media attention since video of police using pepper spray on Occupy Wall Street protesters at the campus spread across the Internet.

Update at 4:22 p.m. ET:

Two University of California-Davis police officers have been placed on administrative leave after using pepper spray on Occupy Wall Street demonstrators on the campus on Friday, the Los Angeles Times reports.

The two officers were the only ones university officials were able to identify as having used the spray in viewings of multiple videos of the scene, university spokeswoman Claudia Morain tells the Times.

The officers' names were not released. They will remain on leave indefinitely.

Campus Chancellor Linda Katehi is convening a task force to investigate the incident and report findings in 30 days.

The University of California-Davis police chief is telling the department's side of officers' heavily publicized use of pepper spray against demonstrators taking part in an Occupy Wall Street protest Friday on the Davis, Calif., campus, the Los Angeles Times is reporting.

Police Chief Annette Spicuzza told the Times that officers made the decision to use the debilitating spray after demonstrators surrounded the officers.

"The students had encircled the officers," Spicuzza is quoted as saying in the Times. "They needed to exit. They were looking to leave, but were unable to get out."

Video that circulated widely on YouTube and Facebook showed an officer dousing protesters with a can of the spray as protesters sat on the ground. The police were attempting to disband an Occupy Wall Street encampment of tents and campers on the campus.

UC-Davis Chancellor Linda Katehi says the incident raises questions. After reviewing the video, she told the Times, "It left me with a very bad feeling of what went on." She added, "There was enough information to show that we need to take a serious look at what happened."
