The Montgomery Police Department is still investigating the viral Montgomery Riverfront brawl that occurred nearly a week ago. A young white woman faces charges, becoming the fourth arrest in the incident.

Mary Todd, 21, turned herself in on Thursday and was charged with misdemeanor third-degree assault. WSFA reported police said the young woman is at the Montgomery Municipal Jail.

Todd’s arrest comes just two days after three white men were arrested and charged for their roles in the fight. Blavity reported that Allen Todd, 23, and Zachary Shipman, 25, face the same charge. However, Richard Roberts, 48, faces two counts.

Authorities have also requested to speak with Reggie Gray, the Black man seen in the footage assaulting others with a folding chair. Police said more charges are expected as they continue investigating the incident.

The Saturday altercation began when a Black security guard had advised a group of white boaters to move their pontoon boat since the area was reserved for the Harriott II Riverboat.

Several videos of the fight had circulated on social media, with one video capturing the worker exchanging words with a white man before another attacked him.

The man tossed his hat in the air, and the fight began as the trio threw jabs at each other. Several white people started beating the security guard as bystanders yelled in the background.

Black people who witnessed the incident from the shore rushed to the scene and helped the security guard. Many hailed 16-year-old Aaren as a hero after he leaped from the riverboat and swam to help fight off the white boaters.

“In the face of adversity, Aaren selflessly came to the rescue of a fellow colleague, showcasing courage beyond his years,” the teen’s publicist, Makina LaShea, said in a statement. “We are immensely proud of his actions and the values he exemplifies, standing as an inspiration to us all.”

“The overwhelming love and support pouring in from all corners of the state and surrounding areas have deeply touched Aaren,” it continued. “Your kindness and encouragement have shown him the power of unity and the warmth of a caring community.”

Black users on X, formerly known as Twitter, praised the Black bystanders for stepping in to help one of their own in a dire situation.
