Bike could have been stolen, A friend borrowed it. Either way the owner wasn't committing the crime. And the girl should have tried to stop him from risking her life and others. At least the cop had a siren and lights to warn people. If this was in the US they would have been on an interstate doing tipple digit speeds. A few years i was on a two lane road(one direction) and a guy on a bike flew past me like i was going in reverse. I was doing 65-70 and if another car pulled into his lane there was no way he could avoid the impact. Stupidity plain and simple.
