A former Scottsdale police detective has been indicted by a Maricopa County grand jury on charges of aggravated assault and endangerment, stemming from a vehicle collision last November.

Michael Lanouar was driving his assigned detective vehicle in November when it collided with another vehicle at Pima and Indian School roads, police said. Both occupants were injured, and Lanouar was arrested on suspicion of DUI. 

Laboratory results showed Lanouar's blood alcohol concentration was .198% at the time the crash, police said.

The case was investigated criminally and internally by the Scottsdale Police Department.

The internal investigation was completed on Jan. 12, and Lanouar was involuntarily demoted from police officer to detention officer. 

Detectives in the Vehicle Crimes and Reconstruction Unit completed the criminal case investigation and recommended charges to the Maricopa County Attorney's Office. The grand jury felony indictment came on March 1, police said.

“Lanouar has been placed on non-disciplinary suspension as the department is re-evaluating his continued employment,” police said in the release.
