A Miami cop was arrested and fired from her job after she shot her gun during an argument with her boyfriend over “inappropriate messages” she found on his phone, according to police.

Sthephany Canizares, 27, turned herself in Friday after initially fleeing when cops arrived at the couple’s home, according to a police report obtained by NBC Miami.

She then admitted to cops that the frightening incident was sparked after she found the texts in her paramour’s phone.

Canizares’ boyfriend told the deputies the pair had been having “relationship issues” for the past few days. When he arrived at the house on Friday, he found her outside holding the gun.

She refused to come inside when he asked, and then she fired a shot from her weapon outside, police said. Nobody was hit, authorities confirmed.

The boyfriend, who has not been identified, bolted inside and locked himself in one of the bedrooms with his young daughter and his own gun.

Hours later, Canizares called the police and turned herself in, handing over her firearm with a spent casing inside, the police report said.

She told investigators the shooting was sparked by the discovery of “inappropriate messages” in her boyfriend’s phone.

Canizares was charged with aggravated assault with a firearm and discharging a firearm outdoors in a residential area.

She was initially taken to a hospital after displaying “abnormal behavior” before she was booked into jail on Sunday, police said.

She bonded out on Monday and the Miami police department confirmed that she has been relieved of duty with pay pending the results of the investigation.

Video shows Canizares singing the National Anthem at a swearing-in ceremony for former Police Chief Art Acevedo in 2021.

She’s also been photographed with current Chief Manny Morales, according to NBC Miami.
