The Houston Police Department posted on X, formerly known as Twitter, about 24-year-old Jonathan Torres' arrest.
Authorities said Torres was relieved of duty on Tuesday amid an investigation.
Charging documents show that the incident happened on Monday when Torres allegedly slammed a laptop on the hand of a woman he's dating.
Records alleged that he then used a handcuff around her wrist to pull her to the ground.
Torres was charged with assault of a family member and unlawful restraint. He was booked into the Harris County Jail.
The department said Torres was assigned to HPD's Midwest Patrol Division in August 2024.
