Bobbie Sanchez said the feeling of privacy disappeared when her child said "Mommy there's a drone over our roof."

Sanchez said it was hovering long enough for her to take photos and then call for help.

"They're watching my children play in the backyard," said Sanchez. "I called the Hurst Police Department and was pretty surprised to hear that it was them."

Hurst police and fire started using drones earlier this year. They said the day they were over Sanchez's yard was a training exercise.

The department is already making changes. Any officer using the drone will now need high-level approval.

"We will not be doing any type of training exercises over houses and things like that," said Hurst Police Assistant Chief Steve Niekamp.
