Does 'criminal' behavior exist in other animals?

I suppose it depends on how you define "criminal behaviour". The reason humans can behaviour criminally is because we have a set of laws or beliefs that governs what is acceptable behaviour. 
We are able to project human qualities on to other animals, for example cuckoos removing the eggs and chicks of the host bird could be considered murder by us. However this behaviour is usually instinctual and calling it criminal would be misleading and destructive to proper understanding of why and how the behaviour exists.  

What you are asking is actually a very difficult question to answer. We need to consider what behaviours are instinctive or reflexive and which are consciously performed. Then if the behaviour is conscious the animal in question must have the capacity to differentiate between "right and wrong". It is possible and rather probable that this occurs in many mammal species, however it's often rather difficult to determine. 

I recommend you read up on anthropomorphism and teleology in animal behaviour.  It will likely change the way you think about animal behaviour and apparent social systems. 

TL;DR: Its complicated... But possible and quite probable, especially in higher mammals.
