We would like to inform you that if your inquiry is related to the existence of a 500 false money paper and you have been informed of the arrest of the accused, the following information are important:
If the CID contacted you in order to attend and gave you a paper in order to go to the court, and you are concerned about this matter, then you shall check the case papers in order to confirm the nature of your legal position in that case.
You may contact the judge's secretary first, so that you could know your legal position in the case and the reason for calling you to go to the court.
If you are unable to contact the judge’s secretary first, in that case it is best to seek the help of a lawyer to find out the reason for calling you to the court, and also so that the lawyer could know your legal position in the case.
Here is the text of the Qatari Penal Code related to your inquiry:
Article 218:
One is convicted to no less than five years and no more than fifteen years in prison and to a fine of no less than five thousand riyals and no more than fifteen thousand riyals in case of forging, counterfeiting or falsifying anyhow, a govern- mental bond, a metallic or paper currency circulating legally in the state or in any other state.
Falsifying a metallic currency is scaling down its metal or forging its coating in a way that makes it resemble another currency with a higher value.
