(NewsNation) — Three white boaters in Alabama’s capital city will be charged with misdemeanor assault for a riverfront brawl with a Black boat captain that drew nationwide attention, with more charges likely to come, police said.

Videos of the incident, which circulated widely on social media, have proven crucial in investigating what happened, Montgomery Police Chief Darryl Albert said.

Albert told reporters Tuesday that three men involved in the incident have been identified as: Richard Roberts, 48, facing two counts of third-degree assault; Allen Todd, 23, and Zachary Shipman, 25, both of whom face one count of third-degree assault, a misdemeanor in Alabama.

One person has turned himself in and the other two have agreed to turn themselves in by the end of the day Tuesday.

Officials are asking 42-year-old Reggie Gray, a Black man allegedly seen using a chair as a weapon in the footage, to come forward for questioning.

The fight was largely split along racial lines and began when a moored pontoon boat blocked the Harriott II riverboat from docking in its designated space along the city’s riverfront, Albert said. The Harriott II had 227 passengers aboard for a tour.

Before the fight began, the riverboat captain tried to contact the pontoon boat owner by loudspeaker. People on the other boat responded with “obscene gestures, curse words and taunting,” the police chief said. The riverboat co-captain took another vessel to shore to attempt to move the pontoon boat and “was attacked by several members of the private boat.” Albert said several people from the riverboat came to the co-captain’s defense, “engaging in what we all have seen since on social media.”

Video captured by bystanders showed that once the Harriott II docked, several people from the riverboat rushed to confront the people on the pontoon boat and more fighting broke out.

The video showed people being shoved, punched and kicked, and one man hitting someone with a chair. At least one person was knocked into the water.

The police chief said so far the charges are against people from the pontoon boat who assaulted the co-captain and a 16-year-old who got involved. Police are trying to locate and question the man with the chair.

Albert said while some made racial taunts, the police department does not believe the motivation behind the fight rises to the standard of a hate crime. Alcohol is believed to be an escalating factor, he said.
