This is what happened when you park your car without pulling the hand brake, and especially if your car is parked near a slope that is next to a huge monsoon drain..

eye witness accounts and squashed grass confirmed the path

Account of the incident:
(as reported by an anonymous source from the neighbourhood)

• a couple parked the car and happily took the LRT to work
• forgot the hand brake, most probably
• at about 1pm, the car slowly slide down the drawn path
• owner discovered the incident after work
• tow truck came but had no idea what to do, a crane is needed
• everyone gathered around and tried to look for the number plate after dinner
• btw, a dude said it’s 2034

Kerol and Horny being busy-bodies

So, ladies and gentlemen, PULL YOUR HAND BRAKES
