Someone tried to steal my bike!

Yesterday, some lowlife attempted to steal my motorbike. They went at the bike lock with a piece of concrete, doing some serious damage. Thankfully, a brave bystander caught the incident on video and notified the AFP. Before taking off, though, the thief threw the chunk of concrete at the bystander and bolted.
Now, I’m hoping the AFP can track them down and make an arrest. In the meantime, I’ll need to replace the front rotor and maybe the brake pads, plus invest in a stronger lock. Although my lock technically survived, its integrity is now questionable—and I've seen photos of similar locks breaking easily when the bike is rolled forward with them still on.
