Cash Machine "crime"?

Apparently these incidences of pushing people out of the way at cash machines are not being classed robbery as the it is the bank not the customer who loses the money but surely there must be some offence committed (if assault can't be proven), to stop this being an incentive to this perpetrator and others to commit the crime if nothing else?

Would it not class as theft from the bank or is that not direct enough as the customer initially loses the money but is then reimbursed.

Just been reading through the comments on the Facebook page of the Manchester Evening News (deep breath needed first though!). Sounds like it may be happening in other areas as well, a few alleged attempts reported around Droyldsen, not that far from where the ones in the article took place.
