Officer Patrick Larrison is a six-and-half-year veteran of the Phoenix Police Department. But he’s just been placed on administrative leave after video surfaced of him tackling a 15-year-old girl who was walking away from an altercation.

Excessive Force? Shocking Video of AZ Police Officer Tackling Young Girl

Officials with the department say that Larrison is the subject of both an internal and criminal investigation. Although the incident happened on January 25, the department just became away of it on Tuesday.

It apparently centers around a young girl who was pulled out of school for drinking on campus with her friends. During a subsequent, and physical, parking-lot altercation with her mom, she started walking away when officers arrived. That’s when Larrison chased after her:

“That type of video is very concerning to us,” Phoenix police Sgt. Trent Crump told ABC15.com. “What you see in the video is of great concern to the Phoenix Police Department about how a member of this community was treated.”

“A charge here in what we’re looking at, is there evidence of an aggravated assault or not,” he said. “We have notified the County Attorney’s Office of the video.”

The names of the girl or the mother were not immediately available. But Crump did say the girl was charged with aggravated assault for striking a school employee and making threats to officers.

Now, he said, Larrison could face a felony charge of aggravated assault himself because his actions involved a juvenile.
