So two tourists broke into an MTR depot in Chai Wan, sprayed graffiti all over some train carriages, and then just... tried to fly home like nothing happened. Police caught them at the airport. Criminal damage, the charge sheet says. Honestly, the boldness gets me. You don't sneak into a working train depot for a laugh. Someone climbed a fence, someone brought cans, someone picked "MTR rolling stock" as the canvas.

Here's the bit that actually gets me: they nearly made their flight. In a city with cameras on every corner and an MTR that tracks your Octopus tap to the second, two people vandalised a train depot and still walked to check-in before anyone stopped them. That's not a security story, that's a "how did nobody notice" story. Somewhere in Chai Wan tonight, a train sits in a siding wearing someone's holiday memory, and two people are explaining to a duty lawyer why the trip home got so complicated.
