Video of a Washington, D.C., police officer chasing and handcuffing a 9-year-old boy on Monday has prompted a review of police practices.

Attorney General Karl A. Racine told news outlets Wednesday about the review into how the department deals with children. He says those practices will then be compared to other departments. The child wasn't charged with a crime and was released into his mother's custody.

The mother says her son was leaning against a car and the officer asked him to move. She says her son then called the officer a slur and fled. Police say an internal investigation is ongoing.

Last month, another officer detained a 10-year-old boy later determined to have been wrongfully accused of armed robbery. Chief Peter Newsham says that launched an internal procedure review.
