Dear Richard,
Sorry to hear that your mountain bike of which you have owned for twenty years has been stolen.
I find it most extrodanary that a crime has been committed and has been captured on video, which obviously shows footage of the incident together with possible facial recognition of the assailants and the Dutch police decline to examine or investigate ?
A frame number should play no part in the process at this early stage .
The Dutch police quite clearly need to review the video evidence in the first instance and act accordingly to carry out a full investigation which will hopefully lead to multiple arrests of the lowlife scum who committed this act.
When they catch these absolute imbeciles , they should have their hands crushed inbetween two gigantic mill stones that you have in all your windmills that sit adjacent to your waterways over there !
Let's see the useless bumberling bafoons try and grab the handlebars of their next bicycle !!!!
Keep your chin up fella .
Cheers, Nathan
