I'm travelling from the UK to the Czech Republic soon.
The UK foreign travel advice for the Czech Republic includes the following (bold emphasis is mine):
Beware of bogus plain-clothes policemen, who may ask to see your foreign currency and passport. If approached, don’t show your money, but offer instead to go with them to the nearest police station. If you suspect that you are dealing with a bogus police officer, you can call 158 or 112 to check their identity. No police officer in the Czech Republic has the right to check your money or its authenticity.
It is my understanding that 112 is an emergency number and checking a police officer's identity doesn't seem like an emergency. Is it acceptable to call 112 in this situation?
