Just after 8:30 last night, Miami Beach Police rushed to Española Way to find a woman who was eight months pregnant in distress. The woman told police she was having severe abdominal pain and contractions after another woman had beaten her in the stomach.

Police quickly found her attacker: 26-year-old Ambar Pacheco, who works as a police officer in North Miami Beach. Pacheco didn't deny the brutal attack on a "visibly pregnant" woman, MBPD officers say in an arrest report.

Pacheco told Miami Beach cops that the victim's boyfriend "kicked her sister in the face." And then Pacheco said, "I saw red and beat the shit out of her."

Miami Beach Police arrested Pacheco on the scene and charged her with a felony count of aggravated battery on a pregnant victim.

The woman beaten by the North Miami Beach officer was rushed by Miami Beach Fire Rescue to Mount Sinai Hospital, where she gave birth. There's no word this morning on the condition of her and the child.

Pacheco has been an officer with NMBPD for less than a year, says Maj. Richard Rand, a spokesperson for the department. She worked as a uniformed patrol officer.

"She's been relieved of duty as of this morning pending an internal investigation," he says.

Rand says he hasn't reviewed her internal file yet and doesn't have any details about whether she faced other complaints in her time on the force.
