My father was visiting Amsterdam and was robbed of his passport and significant amount of cash. It seems the people who did this left his passport and ticket in a cafe next door and the kind lady called him so he could get his passport back but the thief's are still out there who stole his cash. We have a video from the restaurant where this happened that clearly shows the faces of the thieves in the act.
He is a senior citizen who has vision issues, he went through hell and mental agony due to this.
How can we file a police complaint (with the video clearly showing the thieves)?
