(CNN) -- Virginia Tech graduate student Jamal Albarghouti captured dramatic video of the deadly shooting on his cell phone.
He was heading across campus to meet with an adviser, not knowing anything of the 7.15 a.m. dormitory attack that killed at least one person.
He was nearing Patton Hall when a man started shouting at everyone to get out of the way, Albarghouti told CNN. (Watch Albarghouti's video of police officers swarming amid the sound of gunfire )
"I just turned around and left," he said, and that was when he ran into police officers rushing to the scene.
Albarghouti took cover on the ground as ordered by the officers and then pulled out his cell phone to shoot video.
He captured scenes of police officers with guns drawn, moving toward a building. The sound of multiple shots being fired can also be heard on the video.
Albarghouti, like many other students on the campus, was aware there had been bomb threats recently.
"I knew it was something way more serious than that, so I started taking the video," he said, adding that he often visited CNN.com and knew he could send his video to I-Report.
