I got hit today by green laser when approaching BRU just passing Liege. I immediatly reported to ATC, they confirmed the message and did nothing. No police, no further questions asked.
If you report this kind of event in Germany, police will be coming on board after arrival, taking statements and directing units towards the point of occurence according to your statement. Then a report is filed, and after a while you get mail from the state attorney updating you on the matter.
