I lost my iPad at a Tokyo Bus Station

I was unpacking/organizing some items at the bus stop station before leaving for some food for one hour. Then I came back and the iPad was gone from where I set it. I asked the nearby staff to check the lost and found and nothing, I also asked them to review the cctv footage but they refused. The iPad is being pinged on my find my iPhone app every 1-3 minutes currently, its been 40 hours since I lost it. My hope is that there is a way to have them review the footage.
