That's fake :O They can't cancel a visa after they've issued it and after you've entered the country :/ There is no mechanism for that to be done between the ministry of foreign affairs and the thai immigration office.
I'm not saying don't get them the updated police report but I'm saying there's not much they can do if you don't seeing as you already entered and already got the visa marked used and already got the 90 day stamp ..
