We would suggest that you avoid this at all costs. Being in a jail in a foreign country is never good. Do not assume that your country’s representative will drop what they are doing to come to your assistance.
Most of your Khmer acquaintances will try to avoid contact with the authorities; so do not expect them to be front and centre of any help that you need.
Find your embassy and keep a note of it in your passport. There are only 29 representatives in the Kingdom, so you will need to find out who will give you assistance.
The Embassy of the United States can be telephoned on (855-23) 728-000
