Police say a fifth suspect in the Riverfront Park melee turned himself in on Friday, nearly a week after the large physical altercation in Montgomery, Alabama.
Charges were originally filed against three white boaters who allegedly assaulted a Black ferry co-captain on Saturday. Two more people have since been charged in connection with the incident.
The latest -- 42-year-old Reggie Ray -- turned himself in to police on Friday and was charged with disorderly conduct, police said. He is currently housed in the municipal jail.
An attorney for Ray, who is Black, told ABC News his client was "involuntarily roped into the disorderly conduct initiated by a violent white mob."
"Mr. Ray will continue to participate with the ongoing investigation concerning the same and is committed to be forthcoming about his limited role in the brawl," the attorney, Lee Merritt, said in a statement.
Ray's arrest follows that of 21-year-old Mary Todd, who was booked and charged with one count of assault in the third degree on Thursday, according to the Montgomery Police Department.
Two other suspects turned themselves in to Montgomery Police Department on Wednesday, the department said. Allen Todd, 23, and Zachery Shipman, 25, are each being charged with one count of assault in the third degree, which is a misdemeanor, police said.
Another suspect, Richard Roberts, a 48-year-old white male, was first to turn himself in on Tuesday after charges were filed, police told ABC News. Roberts was charged with two counts of third-degree assault.
Montgomery Police Department Chief Darryl Albert identified the victim as Harriet II co-captain Dameion Pickett, a Black male. He also mentioned an unnamed 16-year-old white male who was allegedly struck by the owners and operators of a private boat that was blocking the riverboat from docking.
According to videos captured by bystanders and obtained by ABC News, the fight appeared to begin after a white man punched Pickett. Several other white individuals joined the altercation, which seemed to set off a brawl between those individuals, Pickett and bystanders. Other videos captured by onlookers show that bystanders joined the brawl in an apparent attempt to defend the co-captain, with one man seen swimming to the dock from a riverboat.
Albert also said that police are seeking further interviews with a man who was allegedly seen in bystander videos wielding a folding chair.
Asked if there's any evidence of a hate crime, Albert said that police "looked at every avenue" and left "no stone unturned," but "were unable to present any insight in a riot or racial racially biased charges at this time."
The charges came after police issued four arrest warrants related to the incident and told ABC News in a statement on Monday that additional arrests could come as police continue to review video evidence of the incident.
Police said officers responded to a disturbance at Riverfront Park around 7 p.m. Saturday, where they found a large group of people engaged in a physical altercation and several were detained at the scene.
According to a witness who captured video of the incident, the assault and subsequent brawl came amid a reported dispute over a pontoon boat that was blocking a space of a riverboat.
The witness, Christa Owen, told ABC News Monday that she was on a dinner cruise on the riverboat with her 12-year-old daughter when the incident occurred. She said that after the owners of the pontoon boat were asked multiple times to move the boat they "refused," so a crew member got off the boat and tried to move the pontoon boat himself.
"The black pontoon boat parked where the ferry parks. They wouldn't move when we were trying to pull in. It seems what these guys wanted trumped what a couple hundred people on a stranded ferry needed," Owen said, adding that prior to the brawl, the people on her boat repeatedly asked the people on the pontoon boat to move.
She added, "They just looked at us, decided not to [move the pontoon boat], shrugged their shoulders and left. That's when a crewman disembarked onto a small boat to the dock to do it."
Owen said a couple of hundred people were "stranded on water" until the pontoon boat was moved.
