I wouldn't think that this instance is actually fraud in itself. That'd be way too obvious. It's not that odd that several people picked that sequence, people pick non-random sequences all the time. But what I imagine it COULD be, is that they have some kind of system that can deterministically generate a specific sequence of numbers. So once in a while they can generate a sequence that'll reward someone they know (or every time, but that'd probably be discovered quickly). Someone left that system in a test mode which generates the "5...10" sequence to demonstrate that the system works. But I think it's still more likely that the odds of a lottery somewhere in the world has some kind of interesting sequence is surpisingly high, as others here have said.
