Cobb County police say a man robbed the Wells Fargo bank on Due West Road, but one customer wasn't willing to let him get away with it. <br /> <br />Police say 25-year-old Mark Katchem walked into the bank, and slipped a note to the teller demanding money. A customer, who was inside, noticed what was going on, followed the alleged crook out the door, then ran to his car and grabbed his gun. <br /> <br />Police say the customer ordered Katchem to the ground and held him there at gunpoint until police arrived. Nick Daley was driving by and took a photo of what was happening. <br /> <br />Daley says “I immediately knew by the way the man was standing, his stance, he was in control of the situation.” <br /> <br />When police arrived, they arrested Katchem and charged him with robbery by intimidation. Charise Debarros lives near the bank. She applauds the bank customer for taking charge of the situation. <br /> <br />“It's wonderful that someone is willing to take action and show the bad people out there, you can't do this and we're going to stand up for what's ours” says Debarros
