DAVIS -- Davis Police announced Wednesday that the department has started an internal investigation into an incident on Picnic Day, in which three officers were involved in a brawl with a group of people.
Three people were arrested that day. They have since been released after posting bail.
Since the April 22 incident, a number of witnesses came forward with varying accounts of what happened. FOX40 spoke with one of the men arrested, along with a witness, who claimed the police officers started the fight.
The police department maintains that the officers were attacked first.
Dash cam video released Wednesday shows an unmarked police van make a u-turn and stop in front of a crowd of people partially blocking a lane. Moments later, the fight started.
