A Chinese gentleman used his bicycle in a rather unique way to stop bad guys speeding away on a scooter. Brilliant stuff. Fortunately he was just a regular chap on a regular bike, so using it like this to stop a robbery was a reflex. Leaves us wondering what he would have done if he were a fetishist with an expensive hi-tech bicycle. Choose to protect the bicycle rather than making a "citizen's bicycle arrest"?
We will never know the truth.
