Oh, nothing special, actually.
I found a motor bike on the institute premises. Its front cover was unscrewed. The other professor and I opened the cover to find out that wires are cut to make the engine active without a key.
I called to the police. The police men came after half an hour and checked the bike. Yes, it seemed to be a stolen bike. They took pictures, while I helped them by pointing to the bike, the front cover, and the screws on the ground as the discoverer.
There is a video system installed in the institute, and we checked the video with the police. Three persons came pushing the bike at 5:54 AM. Alas, the video was not clear enough to show the faces. The police said that three motor bikes were reported to be stolen today, and that those three could be the ones.
I gave my phone number to the police.
A year ago, I had my Bridgestone bike stolen, too. So I got my Lamborghini instead. One cannot get rid of crimes in a small city in Kofu, either.
By the way, I got the Lamborghini for free using my Amex points. Point collecting works sometimes.
