There are two types of police in Turkey – civil police and military police, gendarme. In many areas you will see that there is the one or the other, and that both fulfil the same function. In some places, there are also specialist tourist police. If you need to report a crime you should go to the nearest police station to where the crime occurred. In touristic areas there will usually be someone available, who speaks English or you can always request a translator. You will usually be asked to submit and sign a statement. It is advisable to request a copy of any relative document in case you need it at a later stage.
