A Houston mom was arrested after police said she hit her teenage son and dragged him across a room.

According to investigators, the incident happened Tuesday while Grace Guzman, 31, was arguing with the boy's grandmother.

When Guzman's 13-year-old son tried to intervene, police said she hit him with her hand.

The teen sustained some scratches and bruises, but was not taken to a hospital, according to investigators.

Guzman is charged with injury to a child under 15.

She is scheduled to appear in court Wednesday to have an attorney assigned.
