IT has for a long time been viewed as a success factor for police investigation, but now IT has also become an obstacle. Many modern crimes are of a nature where the evidence needed for police investigations is found in both the analogue world and the digital world. We argue that modern criminals act as hybrids, i.e. they are using IT as natural components in their criminal activities. In this paper we analyze the modern criminal as a hybrid and analyze the effect this perspective has on modern police work. The result is that the crime arena should be seen as a hybrid arena, where the criminals and the police both should take the roles as hybrids. Today, there is a division among the police officers, some are acting in the digital world; others in the analogue world. This gives the criminal a bit of an advantage.
