GREEN BAY, WI (WTAQ) - Cell phone video involving Green Bay police is making the rounds on social media.
Now a police lieutenant says the department is investigating whether one of its officers acted inappropriately.
The person who shot the video says it is from an incident after bar close on Friday night in downtown Green Bay.
In the video, you can hear a person yelling profanities at an officer. The officer then pins the person on a squad car and then takes him down to the ground.
Police could release more information on this case later Tuesday.
