BATON ROUGE, La. (BRPROUD) — Four Baton Rouge police officers have been arrested since an investigation into officers’ misconduct started in late August.

The Baton Rouge Police Department Street Crimes Unit was terminated after allegations of beatings and strip-searches tied to a warehouse used by the police dubbed the Brave Cave. The Federal Bureau of Investigation is involved as the police department conducts an administrative and criminal investigation.

The mayor and the FBI are asking for information about allegations of police misconduct.

The mayor and BRPD have given updates since August. Here’s what to know about the timeline of events as an investigation is ongoing.

Timeline of the investigations, lawsuits filed and arrests

Tuesday, Aug. 29

Mayor-President Sharon Weston Broome calls for an investigation into the Brave Cave, which she described as a facility tied to reports of “serious allegations.” In a news conference, the mayor said operations of the building used by Baton Rouge police were suspended pending an investigation.

BRPD Chief of Staff Deputy Myron Daniels clarified the building’s use, saying it was a narcotic processing facility for the police department.

One BRPD officer, Troy Lawrence Jr., resigned.

A lawsuit against Lawrence says he reportedly attacked four people within 90 seconds, falsely arrested two of them and used excessive force while almost hurting other officers who tried to de-escalate the situation.

She directed residents to file official complaints on BRPD’s website.

The East Baton Rouge Metro Council discussed the Brave Cave investigation. BRPD Chief Murphy Paul spoke at the meeting, firing back at council members with a heated speech.

“You strip my funding,” Paul said in part. “Are you gonna pay the attorney all the money that I already owe them for the bad cops that the civil service board where we gonna be here tomorrow and none of y’all gonna be here, and y’all sitting here trying to deal off these people’s emotions and some of y’all the problem, Jen Racca. You sit there, defund, defund the police department’s budget from a legal standpoint, and then come here cause I don’t have legal representation and I gotta play lawyer to fight these bad actors. Let’s talk facts.”

District 8 Council Member Denise Amoroso released a statement, calling on Paul to resign immediately after his “unprofessional” behavior at the council meeting.

Paul was already set to resign in November.
