Six-year-old Eriona Birts, who had been missing since Thursday night, has been found safe in Arkansas, police said.
Birt's mother is in custody, reported News4's Jackie Bensen.
Police had said they were investigating the possibility that Eriona may have left the District with her mother.
Eriona's father, Eric Birts, said he hasn't seen his daughter since her mother, Ebony Anderson -- his ex-girlfriend who was visiting from Arkansas -- asked to take her to a grocery store.
Birts believes Anderson, whom Birts said is legally blind from a medical condition, was driven to D.C. by her boyfriend, 30-year-old Roderick Williams, Bensen reported. News4 learned Williams is wanted by police in Pulaski County, Ark., for a violation of probation that could send him back to prison.
The day after his daughter disappeared, Birts went to a judge and was granted full, temporary custody of his daughter, Bensen reported. A custody ruling wasn't delivered previously since Birts and Anderson were never married.
