MIAMI – A rookie Miami police officer was relieved of his duties after being arrested on robbery charges, the Miami Police Department said on Saturday.

Officer Jose Acosta, 21, was arrested and charged following an internal investigation, reported ABC News.

GovXAcosta had only been with the department for about six months. Yet that was long enough to get himself into serious trouble. He was charged with one count of armed robbery of a conveyance and one count of armed grand theft, the department said.

Miami brass began to review accusations that he robbed victims during traffic stops, WPLG reported.

Deputy Police Chief Luis Cabrera confirmed the arrest during a briefing on Saturday.

The officer was “relieved of duty without pay, pending termination,” Cabrera said.

Miami PD Internal Affairs Division along with the Florida Department of Law Enforcement conducted a sting operation that led to evidence to corroborate the allegations, reported ABC news.

“The city of Miami Police Department will not tolerate actions that betray the oath of our office as public servants and contradict our duty to serve and to protect our communities.”

The department plans to reveal more details at a news conference Monday at 2 p.m. local time. The investigation is ongoing.
