ANN ARBOR, MI - A 17-year-old is charged in connection with a carjacking that occurred Friday, April 7, in downtown Ann Arbor.

Zachary C. Scott, previously of Ypsilanti, but now believed to be homeless, was arrested about 8 p.m. Friday after a bus passenger saw an individual concealing what was believed to be a handgun in his waistband while riding a bus, said Ann Arbor police Detective Lt. Matthew Lige.

An Ann Arbor police officer assigned to the Ann Arbor Area Transportation Authority was alerted by a staff member at the Blake Transit Center on South Fifth Avenue, Lige said. The officer located Scott and recovered a black airsoft handgun from his waistband. A struggle also ensued, but no one was injured and Scott was arrested.

A search of Scott revealed that he was in possession of two additional airsoft guns and a mask, Lige said. His clothing, physical features and the airsoft pistol made him a suspect in the carjacking, which occurred about 1 a.m. in the 400 block of East Washington Street near South Division.

Police say a 30-year-old man was sitting in a parked vehicle on the street when an unknown man opened the passenger door, pointed a handgun and demanded the vehicle and the man's cellphone.

The driver jumped out of the car and the suspect got in and drove westbound on Washington at a high rate of speed before crashing into a parked car, police said. The suspect then fled on foot.

The carjacking suspect was described as a light-skinned black male, between 20-30 years old, about 5 feet 7 inches tall, wearing a dark jacket with a hood. However, Lige said the initial description may have been skewed by lighting conditions and Scott has been identified as the assailant.

Scott also is believed to have stolen a Republic Parking System pickup truck on April 6, Lige said.

Scott has a history as a juvenile delinquent in the Washtenaw County Trial Court. He admitted allegations for various crimes including retail fraud, entry without breaking, third-degree fleeing police, first-degree home invasion, unlawful driving away with a motor vehicle, stealing or retaining a financial transaction device without consent, and receiving and concealing $1,000 or more, but less than $20,000, in stolen property.

Scott has been arraigned on charges of carjacking, armed robbery, felony firearm, possession of stolen vehicle and, resisting, obstructing and assaulting a police officer, Lige said. He was given a $100,000 bond, Lige said.

Carjacking is a felony punishable by up to life in prison.
