Ex-Cobb police officer arrested, accused of sexual assault while on duty

A former Cobb County police officer was arrested Monday on a felony sexual assault charge, authorities said.

Andres Alcaraz resigned Sunday from the police department, and an arrest warrant was obtained Monday against him on a charge of sexual assault by a law enforcement officer, the department said in a news release.

Just more than a week ago, a woman spoke with another officer and said she had been sexually assaulted by an unknown on-duty officer during an encounter in May, the release said. An internal investigation was launched, which led to Alcaraz being placed on administrative leave.
