A YouTube video that has gone viral shows police in Austin, Texas, blasting bystanders with pepper spray during the course of arresting another person.

According to the man who took the video, this incident happened at approximately 1:30 a.m. ET Sunday on 6th Street in Austin, Texas. The witness told NBC News said he he saw a lone police officer push through the crowd and tackle a single person. In the video's caption the poster had said the person who was tackled looked "a little young to be drinking."

After that person was arrested, "police pushed all back and started kicking people too close. Pepper spray/deterrent was used on bystander who was filming the incident, doing nothing," the witness told NBC News.

Officials didn't release details of the arrest, but told NBC News that "the Austin Police Department is aware of this incident, and they are conducting a review to determine if the officer's conduct is compliant with our policy."
