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.
