The group Mothers Against Police Brutality says the arrest of a white Dallas officer in the off-duty shooting death of her black neighbor is a "first step" toward justice and accountability.

Officer Amber Guyger was arrested Sunday on a manslaughter charge and later released on bond. She fatally shot 26-year-old Botham Jean on Thursday at Jean's apartment. Guyger told responding officers she mistook Jean's apartment for her own.

A co-founder of Mothers Against Police Brutality, Sara Mokuria, says the group is happy with the arrest, but believes it should have come days ago. Mokuria says police officers should be held to a higher level of accountability and not afforded special treatment.

She says going forward the group expects transparency and accountability in the case.

Dallas Mayor Mike Rawlings tweeted a statement Sunday night in which he thanked investigators, asked for continued prayers for Jean's family and said he appreciated that citizens and community leaders "were so respectful of the investigative process over these past few days."

The Texas Department of Public Safety says a white Dallas police officer has been arrested on a manslaughter warrant in the shooting of a black man at his apartment.

The department said in a news release Sunday night that Officer Amber Guyger was booked into the Kaufman County Jail and that the investigation is ongoing. It said no additional information is available at this time.

The 30-year-old Guyger killed 26-year-old Botham Jean on Thursday.

Police say Guyger shot and killed Jean after returning in uniform to the South Side Flats, where they both had apartments, following her shift. She reported the shooting to dispatchers and she told officers who responded that she had mistaken Jean's apartment for her own.

The lawyer for the family of a 26-year-old man who was shot and killed by a Dallas police officer who said she mistook his apartment for hers is calling for her to be charged.

S. Lee Merritt, who is representing the family of 26-year-old Botham Jean, said Saturday that the family isn't calling on the authorities to jump to conclusions or to deny Officer Amber Guyger her right to due process.

But he says they want Guyger "to be treated like every other citizen, and where there is evidence that they've committed a crime, that there's a warrant to be issued and an arrest to be made."

Online records show that Guyger hadn't been charged as of Sunday morning.
