One man has been arrested for his alleged participation in the beating.
Dallas police are searching for more information about a "mob" of people who attacked a trans woman in front of spectators who allegedly didn't stop them.
Police arrested Edward Thomas, 29, on Sunday for his alleged participation in the beating, they are still looking for others.
Authorities are calling the crime "an act of mob violence," and are investigating it as a possible hate crime.
Twenty-three-year-old Muhlaysia Booker says she was attacked by a crowd outside an apartment complex after she was involved in a minor car accident.
Someone captured the incident on their cellphone and posted it to social media. In it, Booker appears to be the victim of homophobic slurs and physical violence. The attack was so severe Booker became unconscious.
Several women pulled her limp body to safety. Injuries included facial fractures, according to her family.
Dallas Mayor Mike Rawlings posted a statement on social media:
"Chief Hall alerted me this morning to the assault at the Royal Crest Apartments and I have seen a video of what happened. I am extremely angry about what appears to be mob violence against this woman. I am in contact with the chief and she assured me that the Dallas Police Department is fully investigating, including the possibility that this was a hate crime. Those who did this do not represent how Dallasites feel about our thriving LGBTQ community. We will not stand for this kind of behavior."
The victim's father told NBC Dallas-Fort Worth that Muhlaysia has faced hatred in the past but Friday's attack was the “most violent” yet.
Transgender men and women face deadly violence every year. In 2018 there were 26 reported deaths and two reported deaths have happened this year.
Most victims are women of color.
