Two Minneapolis police officers have been put on leave and an internal affairs investigation against them opened, the department said Friday.

Two sources told the Star Tribune that the incident involves officers Brian Thole and Shawn Powell, who were recently in Green Bay, Wis.,  where Powell used to work as a police officer. The two got into a dispute with two black men and police were called.

The sources said the incident calmed down and no one was arrested. Thole and Powell then contacted a higher-up within the Green Bay Police Department and apparently used racial slurs when describing the incident, as well as sexual slur about Minneapolis Police Janee Harteau, who is gay.

The two officers were both on the SWAT team but have been taken off it.

A brief statement issued to media said only that Harteau had reviewed information related to the case and then initiated the investigation. 

State law prohibits the department from saying anything further, according to the statement.

Cmdr. Medaria Arradondo, head of the department's internal affairs unit, confirmed Friday that he had opened the investigation.
