An alleyway runs behind my dorm. The other day I went back there to deposit stuff for recycling and came upon the police handcuffing some poor fellow. Back in my room, I was curious what was going on. I can't see the alley from my window because of the angle, but I can stick my camera out to take pictures of it. This is what the camera saw. Presumably the perp is in the car. And since one of the officers is hauling away a bicycle, I can only conclude that the police actually chased a person on a bike into an alley, where they captured and cuffed him. The backpack hanging from the handlebars would indicate that they went after a student.
