A 27-year-old Detroit man is in the Roseville jail after robbing a Roseville bank. Police say the man walked into TCF Bank on Little Mack Avenue on Saturday morning around 9:30 a.m. with a duffle bag. The robber then passed a note demanding money to the bank teller before showing her the gun on his waistband. He received an undisclosed amount of cash and fled in a light blue 2004 Chrysler Sebring, which was spotted by police near I-94 and Harper. The Detroit and Michigan State Police engaged in a chase with the suspect before taking him into custody. The Macomb County FBI Gang and Violent Crime Task Force are investigating the incident.
