An internal investigation into Metro Transit Police Chief Ernest Morales III was launched earlier this spring after several employee complaints.

They stem from allegations that Morales created a hostile work environment and negative interactions with women, according to two sources with knowledge of the investigation.

Three formal complaints have been filed against the manager, according to information gathered through a Metropolitan Council public records request. No further information was available.

The Met Council, which oversees Metro Transit, hired Minneapolis-based law firm Nilan Johnson Lewis more than eight weeks ago to conduct a joint investigation, a source said. An unknown number of Metro Transit employees were asked to voluntarily participate in interviews for the investigation.

Met Council spokeswoman Terri Dresen declined to comment on the ongoing investigation, citing private personnel data. Morales could not be reached for comment.

Morales, a New York City transplant, is known for his brash style and has made waves with some employees, particularly women, sources said. During several work meetings this year, Morales has raised his voice and displayed behavior that subordinates consider “bullying” and “intimidation,” the Star Tribune has learned.

Morales appeared on a video call with members of the media on August 6 to announce crime statistics for the second quarter. He appeared on screen in uniform.
