Police review: attitude and manner 1

I am a british citizen currently on holiday at qatar. Recently I have been stopped by the police and asked for proof of identity to show I am a citizen of qatar. However as I am from britain on holiday in this country I didnt have no 'i. D' and also I was not aware I have to carry a passport around everywhere I go just to prove I am a british citizen, however, the attitude the police officer expressed towards us was very abusive and disrespectful. I did not appreciate being kept in-captive in the back of a police van for more than an hour only to be released 3 in the morning after a family member bought the passports to prove our identity. I understand that qatar are strict with immegration service however, the way they treat innocent and vulnerable tourist like myself is highly inapropriate, we have come to the country on holiday to enjoy the life and culture, not kept captured beause they think we are illegal immigrants, I strongly suggest further actions are taken regarding this matter. If anyone would like to contact me about this you can do so on email [protected]@hotmail.com
