A former police chief in Florida was sentenced on Tuesday to three years in prison for ordering officers to arrest black people for crimes they did not commit in order to give the impression that his department was solving crimes, court documents say.

Judge K. Michael Moore of the United States District Court for the Southern District of Florida gave Raimundo Atesiano, who resigned from the Biscayne Park Police Department in 2014, until Dec. 10 to report to authorities to serve his sentence.

The sentencing came just over a month after three officers who worked for Mr. Atesiano when he was the chief were sentenced to prison for their roles in the wrongful arrests.

Mr. Atesiano told Judge Moore in court that he was “not prepared” when he took the job as chief of the department in the Miami-area village of about 3,000 people. “I made some very, very bad decisions,” he said, according to The Miami Herald.
