FARMINGTON HILLS, Mich. (WWJ) -- A Farmington Hills police officer has been arraigned on multiple charges, including domestic violence, after alleged misconduct.

The Farmington Hills Police Department says it received a complaint on Monday alleging that one of their officers had engaged in unlawful off-duty conduct.

After the department's command staff examined the case, they determined the conduct had occurred in the city of Warren and officials immediately advised the Warren Police Department.

On Wednesday, Warren investigators authorized an arrest warrant and on Thursday, they authorized the charges and arraigned the officer, who has been placed on unpaid leave, pending further investigation.

Farmington Hills police did not offer any further information about the case, including the officer's name, but multiple reports say it was 27-year-old Mario Vekic.

The officer was arraigned in 37th District Court on charges of discharging a firearm into a building, stalking and domestic violence.

Vekic allegedly abused his girlfriend of seven months, who is also a Farmington Hills police officer, according to a report from WXYZ. The victim was allegedly slapped, choked and physically thrown around her home.

The suspect also allegedly fired a gun inside the victim's house during a fight.

The victim reportedly resigned from her job with the Farmington Hills Police Department because she feared for her life and is now hoping to be reinstated since charges have been filed.
