Gwinnett County police on Friday released surveillance footage of a man they say cashed more than $13,000 in forged checks.

The alleged forgery took place over four days in late August at SunTrust Bank branches in Gwinnett.

Shortly after noon Aug. 22, the man entered a branch inside a Sugarloaf Parkway Publix and cashed a fraudulent check for $4,765 made payable to Sean Clark, police Cpl. Michele Pihera said.

Four days later, the man allegedly went to two more branches and did the same thing.

In the first incident, he entered a Duluth Highway branch just before 2 p.m. and cashed a fraudulent check for $4,560 made payable to Clark, Pihera said. About the same time, he went to another branch on Duluth Highway and cashed a fraudulent check for $4,240 made payable to Andre Brown, police said.

The names and driver’s license numbers used do not belong to the suspect seen in the surveillance footage, Pihera said. In each case, the man allegedly used a Pennsylvania driver’s license as identification.

The account holders of the cashed checks contacted SunTrust Sept. 28, police said. A SunTrust fraud investigator notified Gwinnett police of the alleged crimes Feb. 23, Pihera said.

Anyone with information about the man is asked to call the police department’s electronic and financial crimes unit at 770-513-5300 or Crime Stoppers at 404-577-8477. Crime Stoppers tipsters are eligible for a reward up to $2,000 for information leading to an arrest and indictment in this case.
