UCLA’s campus, which is a whopping 420 acres, is on lockdown right now as two people have been killed during a shooting in an engineering lab.

Authorities are investigating and have arrived on the scene, and school officials are urging students and faculty to stay clear of Boelter Hall, which is a leg of their engineering school. The two shooting victims were originally reported as “down,” but have been confirmed to be dead by several sources. The shooter is active and has not been taken into custody at the time of this writing.

This is the latest update from the UCLA Newsroom Twitter account.
