Greenville Police are asking the public to help identify a beer thief. Police just released surveillance video of the suspect. They say on two occasions he walked into the Trade Wilco on Highway 264, took two cases of beer, began arguing with the sales clerk, told the clerk he wanted to exchange the beer, then became belligerent and walked out with the cases. The first time the suspect got away with the alcohol, the second time the clerk stopped him. Anyone who can identify the suspect is asked to call police.
