Updated at 3 p.m. Sunday with a statement from High and Tight.

Dallas police said they continue to investigate a "deeply disturbing" attack that left a woman hospitalized, a bartender in jail, closed a Deep Ellum venue for the weekend and inspired protests Saturday night.

About 75 protesters marched in support of the victim in the neighborhood where her beating was caught on a cellphone video that went viral.

"We have to stand in solidarity because too many times, as people of color, we don't have any wins," community activist Olinka Green said. "We are going to let this sister know that we are going to stand in solidarity with her."

Earlier on Saturday evening, Dallas police issued a statement responding to calls from the community for a stiffer charge against the suspect, Austin Shuffield.

"It is imperative that we are thorough and deliberate," the department said in a statement on its Facebook page.

Dominique Alexander, another activist and one of the organizers of Saturday's protest, decried what he called a lack of attention to racial issues in Dallas, saying city leaders had yet to condemn the attack by a white man on a black woman.

"We have to continue to be vigilant against racism in this city," he said. "And we have to stop pretending that racism doesn't happen in this city."

Shuffield, 30, faces misdemeanor charges of assault causing bodily injury and interfering with an emergency call in connection with a violent attack Thursday morning that began with a parking dispute and escalated into a physical confrontation. He has not returned calls seeking comment.

Witnesses told police the suspect knocked the 24-year-old woman's cellphone away as she tried to call 911, and she responded by shoving him away. A cellphone video then shows the man punching her repeatedly while he holds something that appears to be a gun in his other hand.

Civil rights activists are calling for felony charges to be filed against the suspect, including hate-crimes charges. A lawyer for the woman said Shuffield berated the woman with racial slurs.

The victim, who is black, was hospitalized with head injuries.

Shuffield was fired from his job at High and Tight Barbershop in Deep Ellum, where he'd worked on-and-off for about two years, co-owner Baxton Martin said.

"We do not stand behind Austin Shuffield or his actions," Martin said Sunday. "That's the most disgusting thing we've seen."

The venue will re-open Monday morning, after several threats against other employees forced them to hire additional security and lock their doors for the weekend, Martin said. They are developing plans for a fundraiser event to help the victim, he said.

Civil rights activists are calling for felony charges, including hate-crimes charges, to be filed against Austin Shuffield, 30, who currently faces misdemeanor charges of assault causing bodily injury and interfering with an emergency call in connection with a violent attack Thursday morning that began with a parking dispute and escalated into a physical confrontation. A lawyer for the unidentified 24-year-old woman said Shuffield berated the woman with racial slurs.(Ryan Michalesko / Staff Photographer) 2 / 2Attorney Lee Merritt, left, and Next Generation Action Network founder Dominique Alexander speak during a protest Saturday, March 23, 2019 in Dallas' Deep Ellum neighborhood.(Ryan Michalesko / Staff Photographer)

The woman's attorney said she's been in and out of the emergency room because of pain from a perforated eardrum, among other injuries.

"She's scared," Lee Merritt said. "The man who assaulted her still has a gun."

Shuffield was released on $2,000 bond the same day he was locked up. Dallas County District Attorney John Creuzot, in an interview with WFAA-TV (Channel 8), said that proves the need for bond reform.

"Had we been present [when bond was set] and had known more about it, it's possible we would have asked his bond to be higher," Creuzot told WFAA.

The investigation into the attack is ongoing, and further charges could be filed, police said.

"Detectives in this case are still interviewing witnesses and collecting evidence and will determine what, if any, additional charges should be filed," the police statement read.

Green, the community activist, promised that whatever charges Shuffield faces, he can expect to see more protests like Saturday's, whether in Deep Ellum or at his next courthouse appearance.

"We're going to pack that courtroom," she promised.
