I agree that in this case its VERY likely to be fraud.
However, there are many jobs where you might be stuck at work. Being at work == getting paid. Thats not really that shocking of a thing. My wife's dad worked at a children's 'training school' (kid jail) and they often had lock downs or were legally required to have certain number of people on site for certain operations. So he might be there and simply couldn't leave, but might not be 'working'. He was paid for those hours, which I think is pretty reasonable.
