A mother has accused a West Texas police officer of choking her son before a video recording captured the officer pointing a gun at a group of children.

The recent video went viral immediately with over a million views where it shows the El Paso officer clearly grabbing his weapon and aiming at the kids.

The confrontation began after officers were dispatched for a criminal trespass call. Police received information that a large group of children might have been inside a vacant apartment without the owner’s permission, according to a complaint affidavit obtained Monday.

Elizabeth Flores who shot the video said she immediately grabbed her phone to record after the Texas officer started to choke one of her sons. Flores says the video shows two of her sons being taken into custody.

City officials said Saturday that the incident is under investigation. The officer has been put on desk duty.
