The director of a city division tasked with investigating civilian complaints against the Minneapolis Police Department resigned in February following an 8-month investigation that substantiated claims he physically intimidated staff, threatened violence and regularly demeaned female employees, according to newly released personnel records.

The city's Human Resource department launched the investigation less than four months after John K. Jefferson, a retired FBI agent, was appointed director of Minneapolis' Office of Police Conduct Review (OPCR).

A 7-page executive summary of that investigation, obtained by the Star Tribune through a public data request, outlines a litany of troubling behavior, from offensive remarks and unwanted physical contact to overt threats of violence.

In one instance, Jefferson reportedly reenacted a police restraint by putting his hands on a female subordinate, "bending her forward without warning or consent," according to the document.
