CCTV footage of a 'nun' caught on camera stealing beer from a US convenience store is going viral online.The clip, which has notched up close to 150,000 views on YouTube, shows a woman wearing a nun's habit opening a refrigerator full of beer.She is seen reaching for a can of beer then having a quick look around before surreptitiously putting it inside her habit.The 'nun' then walks over to another refrigerator and takes out a bottle of water, which she holds in her hand before returning to the first refrigerator for another beer.It is not clear whether the woman is a real nun or merely a petty criminal using a costume as a diversion.
