Milwaukee Police used OnStar to track down suspect wanted in an attempted bank robbery on the Northwest Side.

 District Four officers responded to Guaranty Bank, 7901 W. Brown Deer Road, around 9:35 a.m. on September 11 for a report of an attempted bank robbery.

The manager of the bank told officers a suspicious person entered the bank about 30 minutes before asking to use the bathroom but never made a transaction. The subject then got into the back seat of a 2015 Chevy Malibu and the car left the scene.

A few minutes later, the same car returned and two approached the bank wearing masks and holding a bag. The manager locked the doors and called police.

Officers ran the Malibu’s license plate and determined the car was stolen back in August. Using the vehicle’s OnStar technology, the car was located in the 3700 block of W. North Avenue. Squads responded to the location and found four people inside the car and took them into custody.

The suspects are a 25-year-old man, a 29-year-old man, a 36-year-old man, and a 28-year-old woman, all from Milwaukee. The 25-year-old man, who was wearing the same t-shirt seen in video surveillance, was positively identified as the person who initially went into the bank before the attempted robbery. Of the four suspects, two of them are convicted felons.
