I live in a block of units which has underground parking (there are individual numbered garages + spare spaces + ample street parking). Recently, someone (I don't know who) snapped my rear indicator light off, left rubbish on the tank and spat on my bike cover (I bought the cover after finding the rubbish). I have a zx6r and I'm the only bike owner here and I only ride it once a week, so I'm not causing noise pollution etc. This morning I found the bike had been pushed forward about 3-4 metres from where I parked yesterday. I'm assuming it's one person. What would you do next if in my shoes, apart from asking for cctv footage? (I've already asked real estate regarding this) Serious answers only please. Thanks people.
