The arrest came a day after police announced they were investigating allegations against Alexander, who has been accused of domestic violence previously.

In an interview Wednesday with The Dallas Morning News, Alexander denied physically attacking anyone. But activists close to Alexander, 30, publicly criticized him after the accuser reported the allegations to the Police Department on Tuesday night.

Alexander first rose to prominence after he began battling the Police Department over the unsolved 2014 slaying of his former classmate, D'Lisa Kelley.

Since then, Alexander has become a fixture at protests across North Texas. He has met regularly with Dallas leaders, including City Manager T.C. Broadnax, Police Chief U. Renee Hall and former Mayor Pro Tem Dwaine Caraway. His partner, Keyaira Saunders, is seeking a City Council seat in Oak Cliff.

Jeff Hood, Alexander's activism partner, said the accuser called him Tuesday night.

Hood said they went to a hospital and then to the northwest patrol division to make the report. Hood, who is close to both the accuser and Alexander, said the accuser was distressed.

"The anger that pervades Dominique is a sickness, and it has to be addressed and dealt with," Hood said Wednesday. "I have seen the good in Dominique, I think a lot of the city has seen the good in Dominique, but I think there has to be an opportunity to rehabilitate that good."

Alexander took to social media on Wednesday to call his longtime associate, Hood, an "agent provocateur" who "must be watched...#snake." Hours before his arrest on Thursday, he thanked those who offered prayers for his family, adding that "God will direct our path."

Hood said he encouraged "the city to pray for the victim, pray for the perpetrator and pray for the redemption for all involved in this incredibly violent situation."

Alexander has been arrested numerous times on various charges. He has pleaded guilty to a felony injury to a child charge. And in 2015, the Arlington Police Department cited Alexander for offensive physical contact against a family member, according to police records.

According to an incident report, the victim called police after a "verbal altercation." Police said the victim told them Alexander began "taking his frustration out on her and pushed her multiple times." The victim also told police she was "offended" but not physically hurt. According to the records, she did not have bruising or injuries.

The victim, according to the report, requested to be transported to a shelter.

Alexander is also currently awaiting trial on a theft charge in Denton County.

His bail on the latest charges was set at $26,500. His jail log also shows Arlington police have a hold on him for the 2015 incident.
