The twins were hospitalized and are in the custody of Child Protective Services, according to NBC affiliate KPRC of Houston.
PRCMcShan said it took authorities several hours Monday to determine which house the twins had fled.
When they arrived, the children’s mother, Zaikiya Duncan, 40, and her boyfriend, 27-year-old Jova Terrell, had apparently left with Duncan’s five other children, McShan said.
"The children were found at a relative’s house and have been deemed safe by the Louisiana State Police.
Duncan and Terrell were arrested after a traffic stop Tuesday afternoon, Louisiana State Police said Wednesday.
