Bicycle detail

My e-bike has been stolen from the official bike parking inside Haarlem
Station.
I arrived on April 24th around 09:15 AM and checked in at the NS bike parking
through the Noord entrance (Kennemmerplein) with my e-bike using my OV
chipkaart.
- I walked straight to the bottom and then turned left and parked my bike on
the bottom left rack, around the middle of the hallway.
- I locked the bike with the wheel lock only (sleutel nummer 869869), but
didn't use the chain. This was the last time I saw my bike and then took a
train to work at 09:20am (according to MijnNS online records).
- When I got back to Haarlem Station at 18:33 PM, my e-bike was not there
anymore.
- I realized that there are cameras very close to the place where I parked
the bike, so I called the NS customer service staff from one of the information phone posts within the parking lot and they told me that there is
nothing they can do to help me unless I reported the bike as stolen to the
police.
- NS customer service also suggested to take a look around the parking before
checking out in case someone moved the bike to another place. I did this
several times, but the bike was not there.
- The bike is black matte with black dubbeltas.
