A 12-year-old and a 13-year-old were arrested at the Ulta Beauty store on Mooney Boulevard and Cameron Avenue at about 6 Sunday night.
Officers say the pair filled up bags with items and ran out of the store.
Officers found the kids hiding in a nearby Chipotle bathroom.
They say the two took about $4,000 worth of merchandise from Ulta.
Their mother, 33-year-old Dequita Harrell, was found waiting in the parking lot.
She was arrested and booked for theft-related warrants.
The 13-year-old was booked for grand theft at the Juvenile Detention Facility, and the 12-year-old was released to Child Welfare Services due to his age.
