Several people were taken into custody Saturday night after a fight broke out at Montgomery’s Riverfront Park in Alabama, authorities said.

The Montgomery Police Department responded to a disturbance at the 200 block of Coosa Street in Montgomery, Alabama, at 7 p.m. after a large group of people were fighting. Several people were detained, police said.

A video of the incident, which appeared to be racially divided, was shared Sunday on social media. It’s been reported that it began because a pontoon boat was blocking dock space needed to park a riverboat. That area is the regular spot reserved for the Harriott II Riverboat.

One short video, posted on social media by Josh Moon of the Alabama Political Reporter, shows several white people fighting a single Black man, who according to Jasmine Williams of WSFA is a dock worker.

The only audio heard is from witnesses yelling, but it appears to begin with an argument between the Black man and one of the white men. Another white man rushes and hits the Black man, who backs up and tosses his hat into the air. Then the fight begins in earnest, and several white people begin hitting the Black man.

During the video, one witness, apparently watching from the riverboat, screamed repeatedly, “Y’all help that brother!” to onlookers who were on shore. It appears some people from the shore did join in to defend him, and the video shows at least one Black man dive into the water from the riverboat.

“Get up there, young buck!” yelled another voice on the video.

By the time the swimmer climbed up onto the dock, about a minute into the video, most of the altercation appeared to be over in Moon's video.

A separate video posted by Lauryn Lauren shows scenes after that, as the Harriott II was preparing to dock. A group of people approached the pontoon boat, and more fighting broke out. At least one person fell into the water from the dock. Authorities were soon on the scene and police began taking people into custody .

Authorities have not released the names of the detained suspects. Charges against anyone involved in the fight are pending, MPD said.
